Found this thread from another one but I think it's a good place to ask this question.
There were times when different "Satoshi Nakamoto" claimers were investigated and arrested, one happened in Germany, another one in Australia and the story goes on. Since it's obvious that satoshi created the forum, was posting here, gave access on forum to other members, etc, because of these reasons, was there ever attempt of investigation on Theymos, Cyrus and other old and famous bitcointalk members?
