Pinterest recently announced that it has begun temporarily locking accounts that display unusual activity.

"The accounts, which 'were associated with a specific piece of spam,' may have been compromised, Pinterest acknowledged," writes Computerworld's Cameron Scott. "But the company blamed recent leaks of user log-in credentials from other websites, rather than a data breach of its own."

"Blogger Josh Davis has been following the issue closely on his site; Pinterest users have been sharing their hacked and locked-out tales in the comments of his July 7 post. ... In some cases, hacked users may lose all their pins and boards, which could be a crushing blow to those who’ve invested tons of time into the site," writes TechCrunch's Billy Gallagher.

"The lockouts follow a couple of weeks of notices that include an 11-question survey to help the company determine what's behind the security breach," writes Threatpost's Anne Saita. "The first note, posted July 10 and titled 'Help! Someone is accessing my account without permission,' suggested first changing the password and deleting any unauthorized pins or boards. It also warned any content deleted by the hackers cannot be restored. 'Please submit a ticket if you have any idea how someone may have gained access to your login information,' the notice said."
