Twitter confirms auto-follow bug
Twitter has confirmed the existence of a bug that can force one user to follow another.
The bug appears to have originally been noticed by a Turkish blog, followed by the blog Webrazzi, which successfully tested it out and forced the Twitter accounts of industry luminaries like Facebook founder Mark Zuckerberg and Twitter CEO Evan Williams to follow a dummy profile. The flaw allowed members to add followers to their own accounts, basically, by tweeting “accept” followed by “@” and any given Twitter user name.
As a result, it’s not yet clear how long the bug had been in existence or whether it could potentially give Twitter users access to the contents of “protected” accounts in which all tweets are private.
But according to the Twitter’s Status Blog, protected updates did not become public as a result of this bug.
Update: apparently the counters of Following and Followers are normal again.
