Where do you get blackhat signups?

I know some people get blackhat signups and then mask the referrer... Where do you guys get these signups from?

 

If you need to cloak or fake anything they are most likely posting on social networks sites or somewhere where that traffic is not allowed.

 

But nobody uses a PTC network or guaranteed signups service to buy the leads?

 

I can't so nobody does that, but most people just get it from not allowed traffic sources like social network sites since those have the most traffic.

Maybe if your doing like those giveaway sites where you need to get points, there's some signup trade sites you might be able to dig up....
