Marketers exploit loophole to bombard Twitter users with spam lists
Yesterday afternoon a large number of Twitter users began to notice that they were being added to a bunch of oddly named Twitter lists.
Lists are normally used to group Twitter users by interest: "tech writers" or "top chefs." In this case, however, the lists had spammy names like GTA 5 Giveaway, Ashton Kutcher's Phone Number, and Candy Crush Saga Hack.
Unlike @ mentions, followers and direct messages, there is no way to block a user from adding you to a list, although you can still report that user for spam. BuzzFeed tracked down a marketer, CelebPhoneNo, claiming to be behind the new method.
