That still should have been communicated to the mods of those communities, rather than just banning with no notice.
I'm surprised that all the scat communities were banned as NSFL without any warning or discussion here. What's up with that?
I think OPs lines are good general guidelines for appropriate conversation about sex with people other than your partner.
I was more lax about sharing details about hookups in my younger years before meeting my SO. It felt much less weird to brag to friends about those details when it was a random one night stand or Tinder hookup who they'll never meet, vs. my partner who they'll regularly see and interact with.
This has a NSFW tag, calm down.
Happy to help contribute to these! I think the tag hierarchy on StashDB is one of the most cleanly organized ways to categorize porn and could be useful here.
Thanks for all the work you've put into the instance - best wishes.
