Suspicious log activity

I was checking my stats at some affiliate program and the number for today was unbelievably big so I knew something was wrong. I checked my logs and here is what I found:

Looking in ARIN's "WhoIs" Database [ws.arin.net], it appears that these are all AOL IPs. But I have no idea what somebody is trying to do. Sorry.
