DangerDave help!

[Cohiba]

Hi DD,
I guess i'm blacklisted at DangerDave.com. Because, i don't receive traffic from you anymore and you don't approve my sites.|sad|
I was submitting my sites from www.sexinvaders.net and www.operationporn.com before blacklisting!
Can you please tell me what was my fault? and What can i do for submit my sites to DD again?

Thanks
