Pinterest Data Breach (2014)

Multiple Pinterest accounts hacked, flooded with butt pics. "Our systems were alerted to some incidents of spam yesterday evening. These reports did not come in at a large scale. We began working on cleaning up and placing the accounts in safe mode immediately. The accounts have since been secured. As a precaution, Pinners should use unique and strong passwords, and can get more information in our Help Center." --quote from Pinterest.
