Clickrisk security experts have identified a growing trend in the form of Paid to Read (PTR) click fraud scams that target both pay-per-click and impression based ad delivery systems.
Among the networks affected are
Google AdSense,
Yahoo! YPN and
AdBrite.
Paid to Read (PTR) scams operate by
targeting home workers and those on low incomes, enticing them by offering cash rewards to join what appears to be legitimate opportunities. The operators of such schemes aggressively recruit these individuals to view and click ads sent to them via e-mail. Evidence acquired by Clickrisk researchers suggests individuals recruited for the PTR scams often go unpaid, although some pay outs appear to be made through the PayPal money service network.
