AOL Hitting Website In A Loop

I have a question regarding something.

I have a live visitor tracking software so I see visitors online in my website

Some hour ago someone from AOL United States was on my contact page website.

Then after an hour i see the same user is still on the contact page but he is going from home domain.com to domain.com/contact.php

Then after 10 seconds he goes again to the homepage, 10 seconds later he goes again the contact page. So the counter shows 1000 pages this visitors is hitting all the same, forwards and backwards, to the homepage and back to the contact page, again and again in a loop for 10 seconds in one, 10 seconds in the other.

So I think this must some user that left his PC on and is going crazy in a loop, has a virus or something abnormal. The IP resolves to a AOL proxy cache using Internet Explorer with low resolution ,536 something.

So I go into the server restart apache, and think this is going to cut or break the connection. No, user is still there looping.

So I say, enough with this, this is not normal, I block the IP. Then voila the user changes IP but same browser from AOL. I say what? Block the new IP and this little devil changes IP again. So i think this must be someone trying to corrupt my webstats or is having fun on me, since a DDOS attack would not be so stupid to use only 1 IP. I block every IP and he keeps changing. So I block the full range from 205.188.116/***
