investigate to be sure we're not vulnerable for such type of an attack. I can't
say we're not at this point.......so THANKS u-bob for the insight...I hadn't
thought of this myself yet....

I will get back on this with an answer on how we think to tackle this problem
You can help stop it by putting in cookie delays. Like if surferA gets a cookie, and returns say 2-5 minutes later with a new cookie, you keep surferA's cookie.

Outside of that, I don't know if it's possible to stop.

I have seen a TGP, do this on all gallery links. When they are clicked, a new window opens the gallery. However the TGP opens an ajax window behind a div layer, which loads the sponsor that belongs to that gallery link.

Ajax can then tell when the browser window is active again, reloads the sponsor, and the cookie is set back to the TGP owner. (the tgp can set a cookie to track returns too) The loads/clicks are broken up to the sponsor because it's done on each gallery click, which is several different sponsors.

I have also seen the direct iframe/frame load of this, which shows jacked up referral numbers, making it pretty easy to spot.

The goal is to target the returns/type-ins to the sponsor, that's a lot of possible traffic to the correct type of webmaster.
