Twitter spammers finally need to beware! Now all Twitter users have a new option, “report [username] for spam” link. When clicked, the feature alerts you that it will immediately block the user and report them to Twitter for review. In the past, Twitter has been using the “@spam” account to allow users to quickly report spam messages via direct message. The “report spam” link should make this process a bit easier and more readily apparent for users of the Web interface.
