I should add, we use ppc daily and I don't find these referrals paralleling any advertising activity. It's rather sporadic, a few one day, more or less on other days. The acitivity started on December 2nd for me.

Coming from some ppc site and they look to be hiding the info so I would contact yahoo on this referral ask for a refund.

Think about it you 2-3 how about a 1000 others hit 2-3 times as well really amounts to some serious fraud money.

2-3 times keeps them under the radar from you and from yahoo. you caught it most never look.

Report it to them as for a refund... I tracked it down to some web development company yahoo will as well.

Here's what Yahoo had to say:

We received your inquiry about the URL alchemy.corp.sp1.yahoo.com appearing in your web logs. That URL is associated with one of our web crawlers, which we use to determine, among other things, the relevance of an ad?s landing page. You have not incurred any click charges from this activity.

hmm I was able to track it to a marketing company so I figured they had some junk on the web. Intresting though I wonder if this is out sourced or yahoo owns the company anyway glad you got to the bottom of it.
