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.
