Hey guys. I've been seeing a lot of pixel ad sites lately, especially when surfing on Clickthru. What's the deal with these sites? Are they good investments, or just a total waste?

it depends on where u advertise on pixads what u advertise on how much money you got.

Just look for a pixel site that gets loads of hits and add an ad that people might click.

I got some good results from originalptr pixel page.
