Yes! Go to settings -> content filters -> filter by channel

You will have to type in the channel name

Oh, that's really not ideal. I'd like to be able to add them to the list from their channel's site.
Anyway, thank you!

You can add a channel to the block list by selecting an episode from an episodes list --- search results list, channel list, or related videos list --- on selection (done by a long 'click') you'll see a popup with the option to add the channel to the block list (bottom of the popup). This works. Although you/me feels that the best/ideal/expected UI choice would be to have the antonym button by the 'subscribe' button on the channel page. But works as I've described which is excellent.

THANK YOU DEVS for this great app and all the effort put on swift and quick updates.

And my shout out to the ether..
With all the AI junk growing like an epidemic, I'd love to have (a) a way to check the age of the channel. And (b) a scaled way to block the AI slop... maybe by sharing block lists!? And, as i've been seeing a lot of videos with the channel name as 'channel Y and channel Z' --- is this really a work by both channels? Or a scam new channel? (c) I'd like to have a way to not crowd the block list ---- the word filter is working for me only with single words.

I cannot say it enough, praise the Devs! Thank you!

Thanks, that feels a lot better.
And yeah, AI slop is why I want to ban channels to begin with. (There's a network literally called The Slop Farm...)
