A DigitalPoint Forums discussion has several cases of Yahoo! Publisher Network publishers being banned in the past day or so from the contextual program. The thread believes there is now a round of YPN cuts, bans, going around at this time.
YPN is known to be very strict on the publishers they (1) allow in and (2) keep in the program, when compared with other contextual advertising programs.
I'll be specific and make Google look bad.
I often spot people scraping content on this site, sometimes, if I have time, I'll try to do something about it.
The other day I wrote an article named Forum Hack Enables Google AdSense Code To Be Placed On Site. Soon after, I saw via a blog search engine, the same content on this site (nofollow added -[sc]) with my content on it. So I figured I would email my AdSense rep to let him know. His response;
Thank you very much for bringing this to my attention. If you would like to file a formal complaint, I have to ask you to fill out the DMCA paperwork. This is the best way for Google AdSense to resolve conflicts such as these.
Um, you see this person is making a mockery of your contextual ad program, named AdSense. But yet you don't want to remove him? Instead you put it on an other publisher to do the work? YPN, I know, would jump on this are remove it asap, if I reported it.
I told Google because I thought they would want to improve the quality of their contextual program. If I wanted to, I could have filed a DMCA originally and not informed Google right away about it.
