I’ve been reviewing some website access logs. In the last week I’ve noticed an unusual event. The referrals on some of the accesses are coming from a common patterned website addresses. But when you go there, you don’t see the linked pages. It’s a great way to target webmasters into visiting squatted domains. You just have to log a page with your website address as the referral to each website that is small enough that a webmaster will take the time to see where the referrals are coming from. Then you wait for visits to your domains, which happen to have adsense or other advertising revenue. A new type of spam on the horizon?
