Best Blackhat Forum

I have a PR</acronym> 4 social bookmarking site and i have over 10k visitor per day.Most of the traffic comes from referring site.Actually

most of traffic comes my website to create backlink.So far i am not
monitoring my site with ad-network.I dont know which Ad-network or which
type ad-network can be best for social bookmarking site.



So far i know ,bookmarking site is not good for revenue .I need to earn few revenue to run this site successfully .

I need a suggestion and i know lot of blackhat member has own
bookmarking site and they run bookmarking site successfully with high
revenue .
