Letting people live in your house in the central business district of a top tier city and then having them comment on your towel designs.
It’s not a hotel. I’m so over it.
Yes I agree, CouchSurfing.com went to shit through a slow process of enshittification that ended up looking like this. That's exactly why we founded Couchers.org when CouchSurfing.com put up a paywall (it was the last straw for us). We're trying to take what Couchsurfing was at its best and go further. We're solving these issues you're talking about with better moderation, better safety tools, and nudging users to behave in a way that's best for the community, etc.
I think it comes down to setting clear expectations and educating users about what it is and what it's not. We try to make it very clear and then enforce those rules very carefully. Once this happens, it's surprising how quickly the community roots out that behavior.
