SEOENGWorldBot

A portion of the UA caught a deny.

Interesting that somebody is running a bot from a private RR IP, in Akron, OH.

71.72.30.zz - - [15/Aug/2012:19:13:44 +0100] "GET /robots.txt HTTP/1.1" 403 559 "-" "SEOENGWorldBot/1.0 (+http ://www.seoengine.com/seoengbot.htm)"

I've a 2009 reference to this bot from Tampa, Fla and a Verizon IP; unique that 2009 offered a newer verson than 2012:

71.100.147.zz - - [14/Apr/2009:21:18:59 +0100] "GET /robots.txt HTTP/1.1" 200 4742 "-" "SEOENGBot/1.2 (+http ://learn.seoeng.com/seoengbot.htm)"

Well, RR has always been a bit iffy. I can remember when they were responsible for half the spam in my inbox.

I'm guessing that they want you to check out their URL and then be so dazzled that you promptly sign up for whatever their service is.
