600 usernames? Am I on that list? While I had absolutely no contact with BFL I was involved with discussions about them, 600 usernames is a lot of people, makes me wonder if they didn't just blanket sopena the entire forum and target all the well known Bitcoiners here.
Theymos would have contacted you if so.
I recently received a subpoena related to a case against BFL (Case No. 14-CV-2159-KHV-JPO). I had to release all database info on a few employees/ex-employees of BFL (including their PMs), plus a complete copy of every thread in which anyone mentioned BFL or in which a BFL employee participated. (It was a huge hassle to put all of this info together.) The subpoena originally demanded all PMs that even mentioned BFL, which is ridiculous, but I managed to get this part eliminated.
If a PM of yours was released due to this, then I already sent you a PM about it.
I don't think that I'm going to send PMs about deleted posts that were released. 3196 users had deleted posts released, and I don't really want to send that many PMs when almost no one would care. I feel like people should have basically no expectation of privacy for something that they posted publicly anyway.
I also released all "report to moderator" reports involving or mentioning BFL. I don't think that these are very sensitive, so I'm not going to send out PMs about these.
