Personally? No idea. They don't tend to publicise it, for obvious reasons. His business dealings have involved quite a few people dying though, including an incident known as the Aluminium Wars. http://www.independent.co.uk/news/uk/crime/abramovich-tells-of-role-in-aluminium-wars-6256950.html You'll notice the name Oleg Deripaska in there. He's one of the guys currently involved in the Trump Russia scandal. That's the kind of people that we're talking about here.
A seedy world no doubt. What did Roman do in all this? Did he kill someone? I'm not saying that he hasn't tread on toes, rich people usually do. Doesn't prove he's done anything though. I bet Levy' s been involved in some dodgy dealings.
Can't be arsed mate. I mean who gives a **** really. So much butt hurt because he chose us over them.
It's not seedy, it's utterly corrupt and evil. He was involved with putting it all together in the first place and having Putin's reign extended when he hit term limits. Levy doesn't have the money or power to go anywhere near something like this. I'm not saying that he's clean, as I've not seen evidence for or against it, but he's not on the same level.
Can't be arsed pops but all successful businessmen tread all over people on the way up, that's how they get there.
