Does not block properly

[ranbla]

I have noticed that many sites are showing up in my feed that I have previously blocked. Is there a limit on the number of blocked channels/videos that the extension will save?

I had the same impression for a while, however, that appeared being not the same channels but the clones with copied content. Mostly, that's spam-bot farms producing such clone-channels. Also, lately, click-bait lovers and all kind of phishing acctivists, those with BS content, create several channel's with little different channel names and using YouTube's 'Collaborative Content' multiplies appearings in the "Reccomended" column frequently. This is the most annoying issue lately, because neither add-on able to recognize nor detect properly those "collaborants", so there's still no effective treatment for blocking them in any form... 😞
