Honestly with everything that has occurred and come out of this, the answer to it is quite simple.

The RP community needs to start better policing itself so there's no further GM intervention that ends up with collateral damage.

Still advertise your venues and events in the PF, we have confirmation now from that email that it is indeed fine to use the other tab to do that.

However, adult spaces? Drop the 18+ and anything alluding to Brothels or ERP, ensure you have an age verification system in place for anyone that "enquires" about Adult oriented RP content, but dont disclude people from your venue if they choose not to verify, you just dont let them participate in any adult activities.

It cleans up the language in the PF

It ensures minors are not wandering in to something they shouldn't be

It protects adults that wish to partake in more adult themed activities (drinking, gambling, etc) from potentially bad situations

And most of all, it should avoid another situation like this happening again.
