PC World, "Pinterest has locked an undisclosed number of user accounts as a result of a spam outbreak, the company confirmed in an email on Friday.
The accounts, which "were associated with a specific piece of spam," may have been compromised, Pinterest acknowledged. But the company blamed recent leaks of user log-in credentials from other websites, rather than a data breach of its own."
Bottom Line: Be sure your log-in has a unique ID and a strong password. ☺
