I am happy you accepted! I made a links page and added Wapchan on Heyuri, you can find it linked on static pages: https://www.heyuri.net/index.php?p=links
UR turn nao, I see there already is a static "Links" page on Wapchan
That's exactly how I think too, net friendships aren't meant to be Serious Business. It won't be anything else than fun!
There is a Discord server, but it's only for post notifications - It's allowing a relatively small userbase to instantly get notified whenever someone makes a new post, and it's certainly not an "off-site chatroom" as one might think it is.
>I don't know if any of these services actually support forced anonymity
There are forced-anonymous IRCd softwares actually, but you would need to set the IRC server (and not just channel) to use them. Or you could create a channel on an existing IRC server of course, but I wouldn't really suggest it: that would attract trolls. If it's just "generating random nicks", there isn't anything preventing anyone from joining an ordinary IRC room with different nicknames each time.
