I know it would be nice to have a little bit more information from him regarding what's going on, but what will harassing him achieve? Is he not aware that people want to know what's going on?
As far as I know you are the first person to bring up harassment. I would not recommend using his contact info for that purpose. Use it to contact him about your losses.
My entire point and premise is that by posting such information you are encouraging (I think purposefully, but thoughtlessly through ignorance is a fine explanation as well) harassment to occur, beyond simple inquiries (still pointless since he isn't off-grid and has indicated he will only respond when he has new info). I referred to it as "doxxing" because in the same spirit that doxxing occurs on /i/, there is a targeted outcome, which is only one of two possible ones. On the /i/ of old, it could be met with pursuit, or the classic "not your personal army" if it didn't mesh with enough of a following. But that didn't stop a few unruly viewers from starting the attack anyway.
This is me saying, "Bitcointalk is not your personal army" based on the fact that I do not believe that it makes logical or ethical sense to team up to harass (or "contact" as you euphemistically have rephrased it) Roman at this stage of the game.
I believe there is more that sufficient evidence to conclude that (1) Roman likely did not do anything wrong other than be unprepared for the bank to handle things this way, and (2) his lawyer has buttoned him up from making any more Twitter promises until things are more clear. Not complying with (2) loses you your lawyer, BTW, in short order. So what would you have him do?
Show me evidence he is trying to skip town, and by that I mean to a different country with a new identity, and I may become more concerned. (And I'm not exactly out chump change here, either.) Until then, your irrational behavior threatens my odds at recovering my assets and everyone else on this forum who has claim to any. Let's say you do goad him into making a bad promise on an email or a tweet, or giving out info that he maybe believes now and becomes false? That opens him up to more civil liability, the likelihood of his lawyer stepping down, and we're all in a worse position than we are now.
I note you are changing your tack a bit -- I say this less to point out that you are "changing tack" as a bad thing and more that, regardless of why, I approve of attempting to politely make contact, and if he requests you desist (which he appears to do on his personal accounts), if you are governed by US law at least (as is Shtylman and Bitfloor LLC), continued harassment actually does become illegal. This is partly due to the US law that currently delineates an LLC or a Corp or a few other things as legally separate identities. I say THIS not because I necessarily have an opinion one way or the other on the need for such laws, or any laws for that matter, but only because like it or not that is the boat upon which we are riding currently.
