The user robortpeter managed to spam our community with four questions within twenty minutes. Each question was heavily down-voted.

To block spam like this, my feature request is to block any user who asks several questions in a row where each one gets heavily down-voted. As an example algorithm: If a user asked two questions within the last hour with a total vote count of less than -6 points, then apply a block for five hours.

This is called "question banning", and already exists. The exact criteria for when somebody gets banned isn't public, but when they try to post they'll get the error:

  • Sorry, we are no longer accepting questions from this account. See http://goo.gl/C1Kwu to learn more.

You can read all about it at that link; it goes to an FAQ post on the main meta

  • Is it on for U&L?

  • @YannisRizos I thought it was on everywhere, but apparently not. We can get it turned on if we start to have a spam problem Oct 22, 2012 at 23:46
  • It's a per site feature, and it's off by default.

  • "users who barely even explain what it is they are trying to do" - sounds very interesting. Is there any site where this is turned on?

  • @Nils At least SO and Programmers; I'm not sure about the others. If you check MSO you can find people asking about it (although a ton of those posts get deleted since they're all duplicates) Oct 26, 2012 at 20:58
  • Nevertheless I think it is a bit extreme. Especially the IP-bound-part. Who does not use NAT at bigger companies or whose provider does not use DHCP with a limited number of IPs? Is there nothing softer, like "if banning were active - your question/answer would be banned"?
