Which websites only have IP-based bans?

Why is it important? Because those are easily avoided so you could break the rules without consequences?

Anyway, because they aren't very effective, I doubt any website will rely on those alone and nothing else.

Start your search on unsecured hypertext transmission protocols. That's http instead of https.

And good luck searching for the next century! 🤣

Haven't you just asked this question on a different website?

None.
