Disallow/Blacklist hashtags

Hi everyone.

I note that there is a section Federation -> Categorization which allows you to have hashtags go to a category, and you can have a post with certain hashtags go into a queue for review, but I don't see a "Hashtag blacklist" where it outright rejects the post.

Is there one that I am not seeing or is that not a thing?

@Crakila hi!

Yes, you've found the right page.

The categorization page allows you to slot incoming content into a specific category.

There are two options (you've discovered one) for you:

1. Check "filter", which causes those posts to land in the post queue
2. Set the category to World (cid -1), which will cause them to stay uncategorized, and pruned out after 7 days.

Right now there's no facility to outright reject a hashtag, but I think you've come across a really relevant use-case that I should support.
