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.
The only bad behavior is from the OP. We just defended ourselves. On the other side, I have decided to halt any campaigns here until further notice, as from tomorrow, since we receive 80% of our business from sites other then btctalk. So we can nicely survive without this permanent bullshit here.
