Hi, I'm not really a person.

I'm a background process that helps keep this site clean!

I do things like

  • Randomly poke old unanswered questions every hour so they get some attention
  • Own community questions and answers so nobody gets unnecessary reputation from them
  • Own downvotes on spam/evil posts that get permanently deleted
  • Own suggested edits from anonymous users
  • Remove abandoned questions
