I will try and give you a real answer b/c for some reason I feel like it today. Anyways, CL traffic is notorious for fraud, so stay away from that. Also, when you mean lure, do you mean trick people into completing offers or provide real advice and then tell them to check this out blah blah blah. The first way will get you banned from all networks. The second one might be alright, as the quality of the traffic may back out, but it is still touching.
In the end, do it the right way. Instead of spamming up those forums, advertise in a legit way to a targeted group of people. But that would just be too easy, right?
