They are changing their IP each time. VSTF made abuse filters against that, Koreans returned with a new tactic. (Remember bаmwar007 spam? I believe those were the same Korean bots that are still spamming) There's no point in making abuse filters further because we can instead catch their current tactic and VSTF can delete their posts without the bots actually noticing their spam is not effective.

@LillieLeve (as answered in chat), their point is to get attention of search engines, not people. Search engines understand Korean.
