As i said their behavior it's pretty bad and it does not help them in any way, yes there might not be a definitive proof of them being scammers but i seriously don't see how acting like that makes your site look any better, you had the chance of clearing your name by showing proof of funds and you didnt want to although you said yourself that one of your priorities is to be trusted and honest.
I am just saying that, although you and your site might be legit, your behavior it's making you look unprofessional and gives your site a bad image, i understand OP might have insulted you and your site but look at your replies to him and others, it's not the way to go.
