We seem to be under an attack from a Korean spamming group. They make a post about every 3 minutes, which gets deleted through flag as spam in less than 1 minute.

Is there a way to stop this at all? Maybe something the mods can do?

Here's such post: https://superuser.com/questions/1488744 (one of the many)

    The messages are in Korean, for what it's worth.

    That link stopped working already, but metasmoke is collecting an archive of them as they arrive. Here is a similar one: metasmoke.erwaysoftware.com/post/201007

  • @tripleee weird, I can still see it if I click the link. It'll tell me the post has been deleted, but I can still see it through the revision history. Anyway, it seems the attack has stopped now.

    If you have enough rep you can see deleted posts, but most of us can't

    "Ah indeed. They're Korean" North or South?

  • Do they use different Korean characters @Moab? I just mistaken the language for chinese when it clearly was Korean.

  • It was an attempt at humor, like it would make a difference anyway, I assume it is South, North would be doing something more nefarious on this site.

I'll try to keep an eye out. The community team is aware and I know they have a very special spanner for throwing into the works here


It's not just this site; MathOverflow, Stack Apps and Ask Ubuntu are under attack as well. Here is a list of those posts. SmokeDetector will cast four spam flags on all these posts (so only two by 'real' users are necessary to destroy the spam), but unfortunately it has a bit of a backlog right now so it might take a while to kick in.

♦ moderators can't do much other than flagging as spam as well; the Community Team can temporarily disable posting by unregistered accounts (though that doesn't help right now, as @Kulfy correctly notes) or try something else. Unfortunately, they have another far bigger problem at their hands at the moment, but I'll try to reach them about this.

  • The link is just to recent posts, maybe link to a slice from a specific time period?

  • I don't think disabling "anonymous" write access would be fruitful. Sites such as Ask Ubuntu require registration for posting.

  • Ah, you're right. The last spam wave I've seen was conducted by unregistered accounts, that's why I was suggesting that. But the Community Managers do have other tools at their disposal.

    For those trying to reconstruct the event, it started with metasmoke.erwaysoftware.com/post/200985 (currently on page 2 of the metasmoke search results for this particular reason) and ended with metasmoke.erwaysoftware.com/post/201177 (still the first result for the search) for a total of 92 posts promoting 16 distinct domains in .net and .com with a link obfuscation using a comma and whitespace.
