One of the benefits of shopping with Amazon is that you are able to read reviews written by other customers before you part with your cash. Now the company has updated its review policy, placing a limit on the number of reviews customers can write in a week.

The new limit means that there is now a maximum of five reviews per customer per week, but there is an exception. If Amazon is able to verify that products have been purchased by -- rather than gifted to -- the reviewer, the limit is increased. But it gets a little more complicated.

Right-wing website Breitbart -- the darling of the so-called alt-right movement -- has been blocked by a leading ad exchange. The site, home to Milo Yiannopoulos (also known as @Nero and banned from Twitter) will no longer be permitted to sell ad space via AppNexus.

The move comes after an audit by AppNexus found that Breitbart was in violation of its policies on hate speech and incitement to violence.

Police are warning people who use dating sites and dating apps to take extra precautions to ensure their safety. The advice comes after serial killer Stephen Port who contacted his victims through apps such as Grindr and Gaydar.

While people making use of dating services have always been warned to take safety precautions, police are concerned that sexual predators are increasingly using such sites and apps as a way of finding potential victims.

Facebook's relationship with China has a tense and turbulent history. The social network is currently banned in China, and this clearly takes a huge chunk out of Facebook's ad revenue. In a bid to keep Chinese authorities happy, Mark Zuckerberg has been involved in the creation of software that can be used to monitor and censor posts made by users.

In terms of playing by China's rules, this is clearly great news for Facebook, and it opens up the possibility of the social network operating in the country. While there is the slight silver lining that Facebook's censorship tool does not amount to a full blackout (as the Guardian puts it: "The posts themselves will not be suppressed, only their visibility"), the new program does raise a very important question: if Facebook is willing and able to create such a censorship tool for China, what’s to stop it doing the same for other markets, or even for its own benefit?

Everyone has a digital footprint these days, and it can be terrifying to think about the amount of personal information stored online in various accounts. You may have resolved to clean up your act and close a few of your accounts, and this is where Deseat.me can help.

The site takes advantage of the fact that many of your online accounts are linked together by a common thread -- Google. By signing into the site with your Google credentials, Deseat.me will find all of your linked accounts and give you the option of wiping them out in one fell swoop.

If you leave a comment on a website you expect one of two things. First, and most likely, is for your comment to be left alone and posted as-is. The second possibility is that you might find your comment has been deleted because of violating site terms. Reddit, however, has a third option.

The self-styled 'front page of the internet' is a little red-faced after CEO Steve Huffman admitted editing comments that were critical of him. Posting using the name 'spez', Huffman was able to anonymously edit comments and replace references to his name with those of Reddit moderators.

Edinburgh-based Skyscanner -- a site specializing in price comparison for travellers -- has been bought by its Chinese counterpart Ctrip. The deal values Skyscanner Holdings at $1.74 billion (around £1.4 billion) and sees the Scottish firm joining China's largest travel site, Ctrip.cn.

Despite the sale, Skyscanner says that it will continue to operate as an independent company, and it will continue to help travellers find the best deals for hotels, flights and car rentals.

The UK government's relationship with the web is something of a checkered one. Keen to pander to the fear of concerned hand-wringers, we've seen torrent sites blocked and there are plans afoot to censor porn sites that do not implement 'effective' age checks.

Now there is a chance that UK web users will be denied access to websites that portray "non-conventional sexual acts" in the latest act of censorship by the government. A bill currently being considered would apply the same restrictions to online pornography that currently apply offline.

Which of these would you consider a daily essential: sex, chocolate, alcohol or Wi-Fi? If you depressingly chose the fourth and final answer, then you probably are a mobile professional, according to a new iPass report, the iPass Mobile Professional Report 2016.

The report surveyed 1,700 mobile professionals, and 40 percent of them choose Wi-Fi. Thirty-seven percent choose sex, 14 percent chocolate and nine percent chose alcohol.  When asked why they gave such answers, three quarters (75 per cent) say having Wi-Fi improves the quality of their life.

The highly controversial Investigatory Powers Bill could be enshrined into UK law by the end of the year after it was passed by both houses of Parliament. Strongly opposed by privacy campaigners, the bill -- dubbed the Snooper's Charter -- will mean a full record of every UK internet users' browsing history is accessible by the government.

All that remains is for the bill to receive royal assent -- essentially a formality -- and it will then become the Investigatory Powers Act. It means the UK will have one of the most wide-ranging, all-encompassing, and privacy-invading mass surveillance programs in the world.

If you have eschewed the big names and opted for a smaller ISP, you probably have a happier broadband experience. These are the findings of a report which says the big four ISPs in the UK -- BT, Sky, Virgin Media and TalkTalk -- are rated lower than their smaller rivals.

In fact, the highest rated provider, SSE, has only been in the broadband game since 2014, with Yorkshire-based Plusnet coming in second place, says Cable.co.uk.

Twitter has promised for some time that it will do more to tackle the problem of trolling, abuse and harassment. Today, the company announces that it is expanding its Mute features, giving users the ability to mute keywords, phrases, and conversations.

This comes in response to feedback from people who have long-asked for a way to prevent notifications about topics they are not interested in, from people they don’t want to hear from, and so on. Twitter also says that it has retrained its staff and improved systems to make it easier and more efficient to report and deal with cases of abuse.

Businesses are often told that the only way to succeed is by embracing the newest, most innovative technologies. The Internet of things, wearables, 3D printing, augmented reality, the list of disruptive technologies that will make or break your organization is never-ending. However, it is often the less glamorous, but more fundamental technology, that actually determines everyday success.

Business broadband, although hardly cutting-edge, is vital in the "always-on", connected world that we live in. No matter what industry you work in, broadband Internet connectivity is likely to underpin many of your daily tasks. Whether you need to stream video files, access cloud applications or simply look something up online, reliable and fast broadband is an essential part of any modern business.

A "terrible error" has been blamed for the accidental virtual killing of a number of Facebook users, including none other than Mark Zuckerberg. Thousands of users of the social network logged into their accounts to find out they were dead after Facebook experienced a strange bug.

The accounts of many people were memorialized as friends were invited to "remember and celebrate" the lives of the "deceased". The mistake led to Facebook users having to reassure friends and family that they were OK and remained alive and kicking.

Google today launches a revamped version of its Safe Browsing site, bringing a number of tools and services under one roof. The tag line for the site is "Making the world's information safely accessible," and Google makes much of fact that it now keeps more than two billion devices safe online -- desktop and Android, as well as devices running Google tools such as Chrome and Gmail.

One of the main purposes of the site is to make it easier for people to report malicious sites they encounter, so other internet users can be warned and protected. But the updated site is also home to additional information from Google, such as its Transparency Reports and company policies.
