Jersey Dude.
I called Pinny to see if I could play while in Vegas and they said no. I didn't try it from there. I would setup my own proxy server had I been in Vegas longer than a week.
Many years ago I asked them this, when I was in Europe, because every year I spend 2-6 weeks, sometimes even more back "home" there.
I was honest, I told them if in USA, I will always use a professional proxy. They said it's OK, that's no problem, plus I am for a long time with them, and have high bankroll there. Now when I made the mistake with the proxy, I talked with 2 people from Pinny, one said I should still use the proxy, and bet whenever I want, the other said do not use the proxy, and only use Pinny when I am outside US.
But the fact is, if anyone is already a customer at Pinny, which means it has proven with documents that is citizen of a country which is allowed at Pinny, if using a professional proxy no way in hell they can know when you are in that country or in USA! You are safe to go, just be careful not making mistakes like I did...
