I tracked down the source of Nocholas' quote (SBR forum), and it seems this fraud ring have already hung themselves by discussing in some detail exactly HOW they are taking money from sportsbooks. It seems they are systematically going through all the Betphoenix skins, multi-accounting all the way, and they are so ARROGANT that they even tell CS that they will "just come back with a different name" if their account gets closed, and another tells CS that they intend to "take them for 10K". The FIRST thing they do is contact support and haggle for the best bonus they can get BEFORE they open the account.
Assuming Nicholas can read, they are revealing a wealth of information about themselves, and their arrogance in that particular thread seems to have caused two "big cheeses" running rival "syndicates" to engage in a "pissing contest" - revealing yet MORE information. One brags that he has just taken delivery of "a container of Eastern Euopean women", so can "do what the ****** he likes with their passports". Nicholas now has to keep his eyes open for a sudden surge of interest in SPORT betting from Eastern European women playing from another country.
The casino fraud may be part of this sports "syndicate", and they may have gone through all the RTG targets one by one, and have now reached BetPhoenix, and will presumably have a new victim lined up now that they have been busted.
This looks like serious organised crime, way beyond the scenario of a friend getting a few mates to stump up their IDs to get extra bonuses (which is itself fraud), and scamming online gambling operators may just be one enterprise among many. Maybe the sums confiscated are of little concern to them, and they would rather keep their heads down than reveal even more by having a deeper investigation done.
I wonder where else they are bragging about these exploits on the internet, and for all to read.
Have they never heard of "Loose lips sink ships" from the early 1940's
..... Loose fingers sink syndicates
