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
And this users are not listed in https://stackoverflow.com/users?tab=voters&filter=all&search=community voters tab.
- How can background process vote this many times?
