I got a phone call from an advertiser on my site. Their stats are showing visitors coming from unusual URL's on my site. I can't find anything in my stats on these, so I don't know how they're originating or from whom.
One form puts words before the "www", as in http
Another just inserts a "a" before the www as in http
Any idea what the perpetrator is trying to do, and how to stop it?
Thanks for any replies.
