[BackDoor Check Request] CAN SOMEONE HELP CHECK THIS

You should always to check for them manually, not asking someone to check It for you.

It's that dumb, as if you would get into some sorta "bad guys pub" and ask dudes from there to hold your money.

Sure, there may be some people who will actually hold 'em for you, but manies will just disapear. Same thing here, If even there aren't any backdoors, someone may add them and send you a file, stating that they're just cleared everything for you.
