Well sir, I guess that is fine.
End of the day you pushed a site without testing it that had huge bugs..
I was nice enough to help you, point them out so you could fix them.
I spammed the fuck out of your site to prove that your spam script was indeed bunk.
Had I actually wanted to rip you off I would have, wouldn't have sent your BTC back.
Also, While you are at it may as well just shut your site down now, Because if I can do this.. Then so can a bunch of other people.
I love the design, I love the Idea.. Just wish the management could see the gaping hole in security they have.
Best of luck sir. :/
