Theymos of the Bitcoin Talk forum today revealed he recently received a subpoena to which he satisfied a request for posts made by current and ex-employees of BFL in addition to the content of their private messages.

He writes (archive):

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.
