From www.myspacepros.com forum, it appears that Google have decided or have been told, not to serve Adwords Ads containing the Trademark 'Myspace'. http://www.myspacepros.com/forum/showthread.php?t=4408
Actually, I was just in myspace forum and all the publishers were rejoicing because they don't want ads with myspace in them on their pages. Those have ridiculously low payout, like 2 cents. So they were happy. Advertisers: not so much.
It remains to be seen whether this is a good thing for myspace site owners or whether it obliterates them due to a lack of ads.
So any ideas when this will come into force for all current Myspace ads? I had a quick look and saw 6 Google ads containing the word Myspace.
Good question, yesterday I didnt see a single ad on my site with the word myspace. Now I have started to see them again.
