Honestly it'd probably be a better idea to just PM an admin discreetly rather than spam their forums with it.
I'm sure if you PM enough admins with "hey this service is being a stuffter and using exploits, maybe you should take a look at it" they'd notice.
No guarantees, though.
One post isn't spam.
Most of the admins have bots that autmomatically answer their pms, so it may not work.
Though if you do pm builderman with the key words "phishing" or something, it might allow you to send a link to the website.
I'll try sending builderman a pm with "phishing" and "bootleg" and other key words, and see if his pm bot will let me send a link to bloxcity.
