The bcentral FastCounter sends out a robot to check your link and verify your site. However this robot doesn't have its own useragent it uses "LWP::Simple/5.48" which is banned by most everyone is a spambot.
Atempts to report this failed because both the chat and email contact forms do not work on the fc.bcentral.com site. I also just discovered that FastCounter free is no longer free unless you had already created your counters before 2005 I have about 15 such counters so mine are still working.
If you have trouble with your counters not working you will have to add the above ip to the whitelist.
