During August 2010, Yahoo has come under a redirection abuse attack by the purveyors of Canadian Pharmacy. This is a fraud operation, and is as Canadian as caviar. There is no doubt that this operation stems from Russia. The evidence leads to one particular criminal in particular, who has been unmasked and publicly revealed as Igor Gusev.

Evidence about this pharmacy fraud exists all over the Internet. One location is the crime sheet at spamtrackers.eu -

It is a shame to see YAHOO! being so slow to act to curb ÿthis abuse. One spam research organization that runs a honey-pot to trap spam has detected over ÿ7,300 cases of distinct URLs from yahoo groups between August 9 and August 18. ÿSorted alphabetically by URL, they range from

They display a >> common image << in a jpg advertising the usual Viagra. Click on the image and you get sent to one of a small set of Igor Gusev's "Canadian" Pharmacy sites

All Yahoo needs to do is to scan all recently added sites and remove all that contain the redirection code to the target sites.
