Traffic through PTC advertising?

Does somebody have experience about PTC advertising? I'm just looking for US junk traffic, not conversions.

I just paid $4.3 for 1000 US targeted traffic and 15s page view from D0nkeyMails, sounds cheap but I haven't heard a word from D0nkeyMails apart from payment completion, even I have sent two messages already...

It would be nice to hear feedback how is D0nkeyMail doing their job.

Don't have any experience with Donkeymails but I've used PTC sites to get traffic for Adsense sites and it didn't really pay off.

I did some ads with donkeymail but it never paid off

Depends on what you're promoting. I use several PTC sites to build my lists for cheap. DonkeyMails offers "guaranteed free signups" which I've used with success on bizopp offers because everyone's there to make money. I paid something like $20 for 100 optins, which I converted into something like $100 in sales up front and then ongoing commissions from email promotion.

Other decent PTC sites include Clixsense & matrixmails.

Btw, Why is this in PPV?
