YouTube seems to be slowing the site for anyone with an ad blocker
YouTube hates ad blockers, and the site has been trying to discourage visitors from using them for quite some time. After introducing warnings last year, the site now appears to be reducing performance for anyone who tries to make use of an ad blocker.
While there has been no official announcement about it, the slowdown has not gone unnoticed by YouTube users. Posts on Reddit reveal the laggy site experience for people using an ad blocker -- lag which disappears as soon as ads are re-enabled.
