FreshRSS needs better filters. I wish I could just say “If [title] contains ‘PREMIUM’ then delete”.

I had not noticed that option! Thank you so much. It did not solve the problem in my original post but it’s still very helpful.

That would be unfortunate if true. Honestly, if I could I would do away with the “read/unread” concept altogether. Are there really people out there who want to read absolutely everything in their feeds?
