Crush little nb=bitches like this who stand in the way of a million- dollar cure to childhood cancer so they can continue to overcharge you for error-soaked software and upgrades, and spyware protection software that actually spies on you (read the fine print!)

But you are the only talentless, lying, cheating, property thief asshole. It is your unique claim to fame.
You're my bitch. Like it or not. Now squeal,

Money obtained by ignoring ethics. And you are proud of it, aren't you.?
You stole that money from someone else.?. Or did you use others' resources to benefit yourself, you worthless fucking parasite.?. Your "talent" will lead nowhere unless you steal from others, and use their resources.

Asshole: I am here in NJ: you are free to come here anytime and try to crush me. Stay there and keep stealing.
Notice how musatov never defends himself from the _SPECIFIC_ charges that he is a thief. He only replies with insults, never addresses the specific claims.
As befits a lie, cheat and thief, who would never accomplish anything using his own resources, so he must cheat , steal and lie , shit all over everyone else's rights, to see if he can accomplish something. 'Cause cheating, lying and shitting on others are musatov's 'Christian Values'; that is the cover for musatov.
But even after ignoring ethics, musatov accomplishes nothing.
