Blexbot Content Scraper is Really Nielsen Media Research

I had great difficulty finding detailed information online about an IP address, 216.176.177.162, that appeared in my site log over ten thousand times. But now that IP address is cold busted. It belongs to Nielsen Media Research, a pack of content scrapers. They do not wish to be identified as such, and so they lie, and call themselves a random name like Blexbot. Tomorrow they will be clexbot, and the day after that, wmu-bot. What are Content Scrapers? They are greedy bots that attempt to grab every piece of data from a given site. Interesting bits of this data are then grouped together and sold to companies, governments, or individuals. In short, they grab content and try to profit from it. They do not send traffic. They should be banned by every site, no question about it.

Lookie what the scumbags are doing on a Wordpress site:

216.176.177.162 - - [29/May/2013:06:21:13 -0800] "GET /password HTTP/1.1" 404 2438 "-" "BLEXBot"

216.176.177.162 - - [29/May/2013:06:21:16 -0800] "GET /signup?context=webintent HTTP/1.1" 404 2438 "-" "BLEXBot"

216.176.177.162 - - [29/May/2013:06:21:18 -0800] "GET /reg/join HTTP/1.1" 404 2401 "-" "BLEXBot"

216.176.177.162 - - [29/May/2013:06:21:21 -0800] "GET /forgot_password HTTP/1.1" 404 2438 "-" "BLEXBot"

They're not just content scrapers, they're malicious hackers. Those 404's you see above? That code means they're making up links as they go along, running them up the flag pole to see if anybody salutes. Meanwhile, the web admin gets to have fun wondering what's wrong with his web site that all of these 404 errors are popping up. (There were many more than just the above examples.)
