if you’re trying to build a chatroom then any chat software goes but if you’re trying to build a community you should probably use something searchable and indexed, like real community software

also i find it laughable that users must already be on such platform, by your logic all communities should be mailing lists

i don’t think it’s unfair to want sustainable tourism, it isn’t either do or dont, there are many ways to do it. think airbnb and rising housing costs: residents may want to have customers AND buy a home in their city
