Write a script to remove editors with confirmed email, but the email belongs to a spammer domain and the spammer domain is in fact verified to be a spam domain. No editors who have OAuth tokens, edits or votes should be removed. All spammer domains need to be verified before being added to this kill list.
Spammer domains are listed in the spam related Google doc.
