This. While everyone can banter back and forth about what is acceptable, this is essentially the crux of the issue. It's been made pretty clear that the GM's will intervene when 18+ events are put up in Party Finder and ONLY in Party Finder. So I don't know, maybe just don't put them up in Party Finder? Legitimately that's all that needs to be done based on what I'm seeing of the GM's feedback. Stick to twitter, Fellowships, discords, or the Crystal RP Calendar to market your events and call it a day. The GM's aren't saying these events are bannable in and of themselves and while I do think there is a discussion to be had about whether or not 18+ material belongs in a 13+ game, the fact of the matter is that the GM's haven't made that leap yet. Stop giving them a reason to do so if these kind of events matter to you.
