Allow a user to provide filter topics in their settings that remove certain topics/post types from their recommendation algorithm.

Is your feature request related to a problem? Please describe.
As a person looking for a personalized social media app, I would like to specify exactly what type of content I do not want to see. This is not the same as "muted words" as sometimes I do not know what words the content will contain - i.e. a racist post.

A risk of this is that users may create echo chambers for themselves this way - but it certainly would make the app more enjoyable for most users. I don't like seeing far right or left content / comments, I don't like junk / brainrot posts, etc.

Describe the solution you'd like
The filter tags should be input into the recommendation algorithm and either use AI or a better method to filter any posts that are scanned to match the post type and not include them in the recommendation.

Please note I do not mean this feature request should include a change to a user interface of course. I am referring to a backend implementation first that can be accessed by a later frontend change.
