Is there a way to permanently IP ban these bots, to ensure that they don't come back (at least, not as easily)?

Most people who bot forums on the Internet are probably smart enough to use dynamic IPs to get around that.

Just make it autoban them if they post Korean letters

Not entirely sure it's a bot, but a random account posting a random google form link is sketchy https://www.speedrun.com/user/6player6
