This apparently has confirmed my suspicions that the problem is definitely with Inktomi and NOT the PFI feeder companies. We had the EXACT same problem with Inktomi PFI through Network Solutions (who was one of the early, more well known name, submission partners). We contacted them about a year ago because we were penalized and after several heated e-mails they INSISTED and GUARANTEED that we were NOT penalized, while it was totally evident we WERE. It seemed obvious to me at the time that the tech support person was lying through their teeth and obviously had no clue what a penalty even was. But now, after trying to deal with Ink, I've been suspecting Ink is in fact the culprit and not treating their partners very well either.
This thread is additionally disheartening in light of the fact that Network Solutions just notified me Thursday via e-mail that they are getting out of the Ink PFI partner biz and transferring my account to Position Tech. I actually thought we might finally get some better service, but I guess I was wrong. In light of this newest info, I think I'll cancel my listing with Net Sol and transfer my Ink listings to Lycos (where my FAST ones are), where I've been getting consistently knowlegable responses.
Maybe Yahoo! will finally get a clue and eliminate Ink from their listings entirely when they start their own new listing scheme, thus making Ink a non-factor. they apparently know Ink is broken and plan on scrapping it and starting all over. Maybe that's why everyone at Ink is so mean, they're too busy looking for new jobs and don't want to bother fixing something which is about to become obsolete.
