Same one that had an unencrypted copy of their entire database taken by the fbi (a server admin had a copy locally to troubleshoot an issue and then got raided)
Could happen to anyone, I guess, but unencrypted is pretty rough, unless it was encrypted at rest and the feds did a silk-road style raid to get their unlocked computer, which seems unlikely.
I used to have a constant rotation of kolektiva people following me and then blocking me like a few days later once they realised I wasn't an anarcho NATOist who wanted to glass Iran
