Best Blackhat Forum

Thanks for the share again
Guys, can you recommend a similar plugin/ system for viral stuff, but to collect emails (white hat).
I'm looking for something similar to upviral . com but with an invite only.

Anyone know what system does growthhackingidea . com use?

Thanks in advance
