Welcome!
Lol! That’s a mouthful!
Checks and neteller are both fine. Neteller has a card you load with funds from your neteller account and you can get cash at any atm with it, Very convenient. But you can’t really pay for anything directly out of neteller except for gaming transaction or peer to peer money.
Checks tend to be so anonymous that I keep getting some that I just can’t figure out who sent them. I am sure than banks don’t know either.
Many many people submit ID. I personally never submit any ID over the internet period. That is just me though. People do it all the time.
Pay your taxes. It is not illegal to advertise anything. Advertising in the USA is covered by the Free Speech law – very explicitly so.
It doesn’t matter where your server is.
I hope this helps!
