Have you seen websites that violate YPN Terms of Service (TOS) and immediately search around to find someone to report to? You must have found no one. This is what the Search Engine Herald reports. “Ever since YPN was introduced they never had an option to report violators of their TOS.”
Anyway, Google is supposed to be more advertisers friendly. By that reasoning, while Yahoo! can turn a blind eye to the advertisers’ losses due to misleading clicks, Google certainly can’t. But the post reports that AdSense is as insensitive to violation reports even though you can report them.
I will assume that there can be difference experiences with Google AdSense. You can’t just send all reports of violations to the trash bin. If you have an experience, share it.
