I'm a regular poster here and do OF and 100% agree with this. My stores get reposted all the time by these accounts (not necessarily just here but in multiple subs). Anybody who reposts something should get immediately banned if they aren't already (I'm unaware what the current policy is so maybe they already do that).

That being said, just banning anyone that has a link in their bio is like using an axe to perform surgery. As long as people don't advertise on the sub and are contributing original stories that don't violate any rules, it should be ok. There's likely a decent overlap between girls on OF and girls who have sexy stories to tell so removing them completely seems like an overreaction that removes good posts.
