Thanks Robert, for some reason I hadn't thought of that :)
I don't know about the reason being "legit" but it makes sense now. Either someone has played a stupid joke on me and signed me up to be monitored from these guys (every 15 minutes it seems), or as siteseer and other services, they hammer you unsolicited then use the stats in their campaign to convince you to sign-up. I emailed them and asked to be removed from their list.
According to the logs, the spiders come from two IPs: 69.93.37.26 and 69.93.37.30. Further digging revealed that they have IPs 69.93.37.26-69.93.37.30 (try accessing those with a browser and you will be redirected to www.webrescuer.com, which is at another location). I added a rule to block all traffic from those IPs (plus sacrificed IP 69.93.37.25, since I was too lazy to make 5 different rules - that IP doesn't seem to be in use anyway, ATM)
/sbin/iptables -I INPUT -s 69.93.37.24/29 -j DROP

Stuff above assuming, naturally, that you have root level access to the server. If not, get in touch with the person who does and suggest these vandals to be blocked. If you are on a shared server it's most likely that all other domains on that server get hit by these guys as well and blocking them will make everyone happy.
Their servers are at ThePlanet, so you could try contacting abuse@theplanet.com to see what the outcome is.
