I set up a public chat room once. It was incredibly good. We banned one guy for posting erotica but otherwise it worked. The problem was the chat was really just a custom "wall" connected to my back end. It was hard to maintain and moderate, and wasn't live.

I tried to replicate that recently with Discord, but Discord doesn't feel anonymous enough.

I would actually love to have something like that again. Just a public chat widget suited for mobile, without needing to learn XMPP or integrating IRC or setting up my own server. Actually an old school chat room would do. I just don't want reacts and profile pics and all that junk.

I'd be quite willing to pay for it too. Not $5/month, but something.
