This isn’t what they said at all, though what they did say, they phrased poorly. They’re looking for hobbiest kink communities for people practicing kink rather than people trying to sell porn. In other places that don’t ban OF advertisements, people trying to participate for the enjoyment of the kink tend to get drowned out by the people trying make a living out of it.
They came off as gatekeepy, but it’s pretty obvious that they’re not asking for free porn to me anyway. Imagine thinking free porn is hard to find if that was what they were asking for.
