PSI/Cogent yet again

Host: 38.100.41.107
Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows XP)

Its getting tempting to just block everything in the range from
38.0.0.0 to 38.255.255.255, because the only visitors I've ever seen from this range are scum spam bots. Typical user-agents include Snapbot, voyager, cfetch, Java, as well as MSIE poser bots. They always run into a trap though, as the one listed here, and that keeps it fun.

Whois:

OrgName: Performance Systems International Inc.

We have had problem with that ip address as well, it's probably an open proxy server being used by different people for different purposes.

PSI is a giant company, this address is used by one of their clients in ARLINGTON, VA. they seem
to provide networks for apartments/offices.
