Actually, I don’t think it’s as much work here as people think, especially if the Admin is earning an income of the advertising revenue. Once ad revenue is involved this becomes a business and the Admin should treat it as such. Most of the other forums are dead. They were seeded in 2011 and 2012 with posts from Terb but few have any volumes since then. Toronto, chat, India and maybe Edmonton have any real volumes and the advertising revenue Is from Toronto area jobs.
Set a policy of acceptable content, get everyone to agree to them, and stick to it. Move off topic threads to the chat, Lock threads as required, delete posts that violate the policy, warn users that violate policies, then temporarily suspend then block accounts that Ignore the warnings. All the racist and nazi shit shouldn’t be allowed and there are hate speech laws around that. If the Admin is actually letting it remain he is then perpetuating it (like the editor of a newspapers) and he should be equally held to account as the poster. If the server host is informed and worries about their culpability (they are also perpetuating it) then they could shut the whole board down if they see any legal jeopardy of their own.
