As for Language Computer, didn't realize some would consider them evil... They paid me only a small visit & were well-behaved. (Actually, until your message, wilderness, I thought them to be human...)
When they visited, they came from 216.138.75.50 - Those looking to ban Language Computer by IP would want to block the range 216.138.75.48 to .63
I paid them a visit & tried their "Question Answering Internet Demo." Earlier tonight, I found a fistful of old Brazilian money, so naturally I wanted to know what kind of goldmine I was sitting on. :) I asked, and the first result back had a great answer - of sorts. Seems the goldmine is worth about $10 American. :( I was on the third SERP at Google before I found an understandable English answer.
NOW - before I'm accused of being off-topic...
Cyveillance - www.cyveillance.com - is EVIL. They:
A) Visit you fast & furious
B) Masquerade as "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)"
C) Disregard robots.txt
D) Parse your HTML for links within comments & then visit them
E) Freaked me out the first time they visited. ;)
They attempt to use my resources to generate their revenue without first seeking my permission, non-compliance of my TOS nor any offer of sharing in the profits, using my bandwith in the process.
Why would you NOT consider that evil?
