YouTube tries to figure out what I like but I often find the channels it recommends are far from my cup of chai. Block YouTube recommended channels is not easy task but I recently got hold of the Video Blocker extension.
Click on the ” Add to Chrome” option to add it.
Once it’s installed, search for the offending channel on YouTube and right-click any video thumbnail.
You’re offered the option to ‘Block Videos from This Channel’. You can even manage your block list using the Video Blocker icon located in the top-right corner of the browser.
You can also hide videos from multiple channels at once, by using a wildcard or adding regular expressions.
Channel and keyword items can be added with a regular expression by using the format /pattern/[flags]. The flags at the end of the format are optional. Regular expressions will not work for wildcard items as they are actually a simple kind of regular expression by themselves.
Blocking videos with certain keywords in their title is also possible!
Comments will also be blocked the same way as channels.
Where is my blocklist being saved?
The blocklist is only saved locally in your own browser, or, if you have enabled that, in your account that you are logged into in your browser (Firefox and Chrome only).
YouTube has become slow after using this extension, why?
For best performance, the newest layout should be anabled on www.youtube.com/new. However, if you have a lot of items in your blocklist, performance can decrease as well. Every video shown on the page needs to be checked for every item in the blocklist, so the number of iterations will grow rapidly. Unfortunately, this is not something I can do anything about.
