There is nothing pointing towards anything obvious.
Maybe not for you, but for me its pretty obvious at who he aimed that post. I doubt he would return to the forum after more than two years of absence to call theymos an anti-privacy shill and call him someone who is advocating for government censorship
Or maybe its just another alt account from someone who is pissed off that mixer campaigns got banned? It woulndn't be the first nut accusing theymos of crazy stuff like working with goverment etc. General sense, isn't it?
You know how they say, problem with common sesne is that is not so common.
