Works well enough for me. I've been using it for about a week now and have blocked many unwanted videos and channels. I would've given it full marks but for two things: Having to open configuration and add a regex becomes a chore, and I wish that blocked channels & videos could also have fed through to youtube's native 'Not interested' & 'Don't recommend channel' functions.

Update: 2025-07-25
As mentioned by several users recently, the block button no longer shows up next to the channel name; not only has this button disappeared, but channels in my Blocked users/channels list are appearing in my feed again (this would probably been much less of an issue if this function had been wired into youtube's native blocking functions, as mentioned in my initial review). I have the latest update installed. Can this please be fixed?
