Report for Spam on Twitter
Folks can now help conquer spam by calling the attention to a profile they find questionable. Click the “Report as spam” button under the Actions section of a profile’s sidebar and the Trust and Safety team will check it out to see what needs to be done. No automated action will be taken as a result of reporting a user as spam (in other words, it can't be used to incite an angry mob against an account you don't like.) And once you report a profile it will automatically be blocked from following or replying to you. You nailed it!
