Don’t be disingenuous. Genuine consent practices also consider that not everyone else consents to witnessing their play, so they don’t do it where it’s not welcomed. And it’s not welcomed on Blahaj Zone, in this case. That’s all.

is this concern based in fact, or emotion?

Ada was clear in another comment thread that yes, emotion was absolutely involved in her decision. That isn’t a bad thing. Why is there a social attitude that decision-making is only valid if it’s cold and unfeeling?

Personally I’m in the camp of “let consenting adults do adult things”

Me too. I don’t think anyone is arguing against that. Anyone can still access LemmyNSFW’s content elsewhere, Blahaj Zone simply isn’t going to relay it anymore because some of it is incompatible with Ada’s goals in nurturing this community.

But if it is in fact legal, and well moderated, then is there a problem?

Yes. Legality has nothing to do with acceptability. This instance already bans lots of content that doesn’t actually violate any laws. It’s a judgment call.

A “gotcha” I just discovered: even though the selector uses radio buttons (which usually means you can only choose one), this is a multi-select list. So if you don’t also choose English (and/or other languages you understand), you’ll miss content that does have a language tag.

Designing UI ain’t easy.
