I dont think its got anything to do with “affiliate sites” thats just conjecture by conspiracy theorist 
So let me conspire for awhile :rollever:
I think since I didnt transfer over to sitematch I was put on a blacklist and banned! Horrible to think, but it adds up for me!
I recall getting several emails about the time they were switching over telling me about the great deals they could offer if I transfered over – of course I didnt and today EVERY site that I had submitted PFI into inktomi is now GONE from yahoo!
PLEASE note that my sites are also gone from every one of the other engines that PFI was supposed to get me into …. very telling!!!!
I do NOT operate any link farms! ALL my sites offer unique content – and yes of course they contain affiliates links, but I dont think those links are reason for exclusion.
I wrote them earlier today – hopefully I can get a response early next week – if not Ill email them again! Then I will call!
If their attitude is “if you dont want to buy into our product we wont give it to you for free” then I am going to be pretty Fn irritated! For sure this is looking like the case to me!
Time will tell ….
