Dear @Theymos Sir <...>
LMAO.
This kind of topic should be avoided for legal purposes, although we exist here anonymously having to question or call out another forum member because of their position in the forum and requesting he either reveal his identity or the identity of another forum member is something that is out of your power, you may be sued for that.
No, there is no legal basis for sueing the OP. On what basis, according to you?
I think theymos allows this thread because he values freedom of speech a lot and also because the thread is going nowhere. I would bet heavily that theymos is not going to intervene in it and that it will simply eventually disappear from the front page of this section because it's just another thread trying to find out Satoshi's identity, which is not going to get anywhere.
