I think what they are doing is the new users that dont know that btc-arbs.com is a scam are still depositing BTC, and they are taking those deposits and paying out some users to mitigate going "full gox" on everyone.. that is why they are processing all those mBTC transactions so people dont panic. I'm telling you we should get as much info about this site while they are still up and running....
What do you mean by getting as much information about them while the site is up?
It has always been such a lost cause at getting admins caught. Not just how anonymous the industry has always been (this is the reason why payment processors for HYIP's have been the ones in the past to ever get arrested) there's always a new one that pops up and people simply forget about the last one. And then there's the fact that hundreds of successful hyip's probably thousands even a remote success come and go - in general a single program that is extremely successful only goes through maybe a few millions bucks 5-10 million for the more successful ones. No government has ever pursued the hundred and thousands of successful HYIP's. They go for the processors about once every 5-7 years.
