Uhh, MLB isn't going to go after you. They aren't going to turn you over to the feds.
WORST case, they close your account. You obviously have no clue about internet crimes, hacking, laws.
For the FBI to even look at a case, there has to b e $5000+ in damages. That's to even look at it. If MLB went to the FBI and said joe smuck is watching brewer games from home with a proxy, they would laugh in MLB's face.
Not to mention the bad press of jailing some dude for watching a "blacked out" game from his computer (paying legally for the service I might add). With steroids, that's all MLB needs. Lets sue customers! Who aren't making any money off it, and probably not even hurting any.
Again, use a proxy for MLB all you want. You get caught, they shut your account down. They WILL NOT prosecute you. You have to be an utter moron to believe that they will. MLB is quite happy to have people paying 17+ bucks a month to watch tv on their computer.
Lastly, it's quite easy to track proxy usage. In fact, a 5-6 year old kid could probably handle the job. If magically you're connecting from Korea, but gee your billing address is Milwaukee! Wow sometihng is up! You can find the physical location for IPs easily, and if MLB wanted they could easily become nazi's and suspend accounts all over.
Infact, they want more customers, not to witch hunt down people. Now if you're selling games, re-broadcasting, then yes, you will get nailed like a school girl. But using a simple proxy to watch your home team isn't going to land you in jail. If MLB found 3,000+ brewer fans watching from their comp with a proxy, then yes they might shut down accounts or send out mean warnings. They want people in the park. BUT baseball won't, and never will, go charge someone for doing it. 1000s of people do it, it's easy to detect, yet no one has been charged? MLB isn't stupid.
So relax and stop trying to scare people.
