Does this not qualify?

You can take a look at Mero.chat. It’s a chat-with-strangers service. You earn more features the more you use it.

Find an MMO that runs on whatever potato you have or can afford. Then join a guild. Then participate in raiding.

That can potentially kill a few birds with one stone.

here? or irc?

Emerald Chat is apparently the new Omegle alternative

NOIYS sorta counts ? Functions like text-only bulletin board type thing ?

Tends to have lotta kids on there tho if that's concern for you
