Having read that whole thread, I can't help thinkin that whole thing was nothing more than the Serbian cops thinking they could squeeze a good kickback out of somebody, and raiding a call center they thought was a server farm.
I looked into doing business over there in the balkans. Serbia and Montenegro do have, uh, what they call "licenses" for about $10k a month... batteries not included... or apparently you can just grease johnny law when he shows up at your door every tuesday. Not much benefit to the customer or the house in doing business from a place like that. Especially to save some rent on running a call center.
Someone in that thread raised the possibility that no one knows if the servers are actually in Serbia. Just from my own research on it, I'd say that's almost impossible. You can't get that kind of bandwidth or infrastructure in the balkans. There are blackouts, you need backup generators... the fastest line you can get is like a bundle of DSL connections. I seriously doubt they're running any critical parts of their operation from there.
