>>> why they don't toddle off to these wondrous non moderated sites they speak of
Yes, they all join the newsgroups that ran alongside, but separate to, the worldwide web in the early days of the internet. Oh, hang on though, didn't they all grind to a halt because of spammers and trolls?
Oh well, there's always Yahoo Groups, which largely replaced them. Oh, wait a moment, didn't they suffer the same fate?
For a Q&A site, there's always Yahoo Answers. Er, but isn't that just full of spammers and trolls these days too?
Of course, Answerbag is another alternative. OK, it got shut down because of the spammers and trolls but the people who then bought it out promised great things from the revived site (but which is now full of spammers and trolls again).
For a chatroom, especially for us oldies, there was Sagazone but, surprise, surprise, it got closed down because of spammers and trolls.
Of course there are still thriving social media sites, such as Facebook. There can't be much moderation there, can there? (Except, of course, from the SEVEN THOUSAND moderators, who're all FULL-TIME, PAID employees of the company)
