I wondered about the cert service angle, but the site it hit doesn't have anything related to a cert, or e-commerce, or https, etc. Will be interesting to see if it becomes a routine visitor, w/ or w/o UA.

Here's a 2003 link [webmasterworld.com] from Jan's old reference file.

Comodo do firewall and AV software - could be a user - but they also have a search site.
A little identity confusion at comodo.com? Yet another UA:
search.comodo.com COMODOspider/Nutch-1.0
robots.txt? Yes

This time, the same UA -- but via a 'bare' (no rDNS) IP:
114.255.52.163 COMODOspider/Nutch-1.0
robots.txt? Yes
114.255.52.163 => China Beijing Comodo (114.255.52.160 - 114.255.52.175)
Internet security/firewall/antivirus/SS/whatever company spidering from China? Oh, the irony!

This bot has hit my server several times looking at SSL certs that are linked to validation scripts that show when the SSL cert expires. I have also been sent several emails about 90-days before my SSL cert expires offering to renew it with them. Once these folks even sent me an email warning me that there was a security issue related to my cert/server configuration and even though the server had been upgraded over a month before that they still claimed it was vulnerable.
Personally I find this type of spamming much like ambulance chasing lawyers and I for one will NEVER use their certs because of it...and now I block them from my server as well and like magic, no more spam from them either..Go figure!
