the top #10 spots are paid ones, top 3 spots costs much $$$ but they return at least the double. The top spot i got is 14th placement with a fetish gallery,i got 140k+ traffic and one trial canceled
Most probably though sometimes Hun lists for free sites above 11th position. There's a site where refers for someone that is interested on buying spots on TGPs and Hun's is one of the listed. Since Hun reads the board occasionaly, you might get a more reliable answer. You can also contact him through his site where he refers to advertising.
