[Question] How to block posts from my feed that have more than 5 Hashtags?

Solved. use ([#].+\n*){4,} on the RegEx visual editor to put a cap of the max amount of hashtags a post can have for it to show up on a feed.

OG question for archive:
I'm currently maintaining a feed for Monster Hunter stuff on BlueSky, but I'm running into an issue where some users would spam 90 billion tags that are not related to Monster Hunter but they include the hashtag we use, so it shows up to our users and it's pretty annoying. Is there any way to remove posts using Skyfeed if the post has, for example, more than 5 hashtags?
