This morning I noticed a HUGE amount of hits from a site I never got hits from before. I went through the stats and took a look at some of the pages the hits came from. They're all forums pages. These pages have coop ads at the bottom that look like they're mixed in with static ads. I was only able to recognize them as coop ads because I recognized some of them, and there is a static "free advertising" link to the coop itself. I suppose it's normal for coop ads to show up as referrals from time to time, but these pages are suddenly accounting for over half of my referrals this morning. So I have to ask are the legit referrals, or is someone spamming my stats page? Not that it will do any good, my stats pages are not public, but it is a pain in the neck.
Yes, they're all from the same IP, and are all almost exactly two hours appart starting just after midnight and going until about 8AM pacific time. They're from Germany, so for them it happened during the day.
