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
