as the title says if i donated on BTN will i get invite however my user class ...and another question if i got invited by staff member and signed from a banned country then i donated would they keep my account ? wouldn't they disable it ?

Hi, you got invites after donation but you can use it only in Master class.

What about your signup issue, better don't atract attention to you. In your situation, I won't donate BTN to keep staff away from me.

but if i donated they may leave my account should i sign up from another country and then change ip to a banned country

Donations don't let you break the rules. If you signed up from banned country you've already done it. Feel lucky your account still works. When they ban it, registration from allowed country and then use it from your home won't helpyou. You may be banned for ip change. Better use your account from VPN or seedbox.
