About etraffic911, I myself own & offer visitors/traffic like that at http://igotsoloads.com/traffic/
Even I have used it to promote my affiliates links. Visitors are real,
but user must be wise where they send this kind of traffic.
I mean, if it is a long time loading page, or a long sales letter or a
signup (squeeze) page it should not work, because people dont
have time to read it at all: mostly they are popunder or popexit,
so if dont call attention from the visitors, it will be closed.
But it will work with an attention grabbing splash page (it load faster) that will send
your visitors to your landing page (sales or squeeze page), and this landing page
will be opened till your vistors close it, so they can browse it, read it, make a signup or even better: A SALE.
