This site is closely moderated, and the mods do a pretty decent job of removing promptly any offensive, insulting or threatening material. By so doing promptly (a key attribute), it encourages us to know that trying to post stuff like that isn't worth the effort. Jeremy Keith polices his Session website closely and assiduously, and members know that it simply isn't worth trying to post nonsense. Dick Gaughan's former website, the same (good old Molly...) You call these social media sites, Dave, and I suppose they are in a way, though I don't generally class them as such meself. Compared to behemoths such as Facebook they are tiny. In a way, that makes my point about too big to fix. BWM highlights one aspect of that, and another aspect is that smaller is more beautiful and more fixable. It would take an army of moderators to police Facebook as effectively as here. Two points about that: first, Facebook can well afford an army of moderators, but has always preferred profit over people, and why spend your profits if you can get away with not doing? Second, an army of moderators keeping Facebook clean and safe would have the far-right and the conspiracy theorists, and all the other multifarious do-badders who use it, deprived of the mass audience they so easily exploit, ranting and raving about the denial of democracy and free speech. It's gone to far to fix, it's too big to fix and it won't be fixed. Maybe a mass revolt and a rapid bleeding away of its members voting with their feet will be the only way. There again, I think I may be in cloud-cuckoo land...
