Few days ago I saw a venue with like 5 ads in PF. I think this should be considered spam, I don't mind the venue ads but why do you need to copy paste the same thing.
I don't think it warrants a block/mute since I honestly think that's a waste of blocklist space over something so...trivial. Give them a roleplay tab and allow people to actually filter/opt out of it. Then you get people who want to advertise a venue/RP event with people seeking that kind of content or looking for it..
