In the Picture Posts Filter, only enable 'Posts with at least one picture', and disable Text-only posts, and you'll see this row appear.

You could do something like this to set single letter boundaries by clicking 'append ignore combination'.

If you don't click 'publish' for feeds on there, it wouldn't be public. The UI is a bit confusing.

See the big Publish Feed button below

I've set up something that seems to be working under "Mode: Responses".

You can observe responses to posts in the everyList and filter out responses from users in the blockList.

Try it out, and let me know if it needs tweaks or drastic changes.

Hey. I see that you did not add the keyword. You need to tap the Green Add button (circled in blue). Once the keywords are in the list, it'll be added to the list (circled in black).

Hey @mizer.bsky.social I'm checking your feed made with blueskyfeeds.com and noticed that it's a feed of your posts sorted by Like. You could try switching to the new user post feed by setting your feed like the picture shown below.

1) Mode: User
2) Sub-Mode: Posts
