Agree with others, banning feels too far, but need to at least be able to filter them out

Additionally, not sure how easy/reliable/worthwhile the implementation would be, but I think it'd be good to reduce the unique trader bonuses the market creator gets for them

Same goes for basic coinflip markets imo

I don't like the idea of banning them, but I wish there was some way of heavily discouraging them

I think there should at least be labeling, so people who don't like it can by default filter out these questions. Same for subjective or personal questions.

@ErwinRossen arguably there are already tags for self-resolving and personal, but yeah I don't know of a way to view all markets except a set of specific tags

Banning things just because they are boring is extreme.

It might be boring for you, but a new experience for new users - they cannot participate in old self-referential closed markets, so they create new.

I think it's ok if some level of creativity goes into making it different than the rest, but yeah when it's just a plain one it's boring af
