Holy crap, posting his mother's info seems a little over the top.
And wrong. Period. Thank you for sticking up for what is right.
This thievery is not chump change. A lot of people have been hurt.
Send *polite* email, tweets, facebook, snailmail, etc. to any of his family, friends, employees, school teachers, and acquaintances that can be located. Tell them what has happened and urge them to persuade the thief to return money.
Pressure can be applied without harassment or threats.
+1 on that.......the best way to get this situation sorted is to keep calm, and get organised.
I've lost nothing (well, 0.2BTC or so, so not a lot) in the MintPal/Moolah scam, but this sort of shit scares people away from all crypto, as well as hurting crypto community members directly.
This may be the Wild West, but guys like this Ryan character (or Mark K, etc...) need to be tracked down using the law, not vigilante action on a forum.
I'd suggest that everyone whos been affected by Moolah/MintPal get together, appoint some spokespeople, make a list of people who have lost out
and who are willing to go into a UK courtroom to prove it, then raise some funds and get in touch with a good UK lawyer to take Ryan on, preferably one with a background in crypto.
Lots of reporting Ryan to the cops will possibly be useful, but I think the only way to get Ryan into a courtroom will be a private prosecution for funds recovery, I can't see the police going to the effort of prosecuting him themselves, unless there is an organised group with legal representation pushing the case forward.
Don't forget this is crypto, what seems simple to us is voodoo for the man in the street, incuding police and lawyers.
