A research company studied some web-habitats of Fortune 500 companies and came up with an interesting find: a full third of the companies studied have preemptively purchased website names with negative connotations, in order to keep the domain names out of the hands of people who might setup unflattering, critical websites.

For instance, 35% of the big-dog companies have purchased [companyname]sucks.com domains, like, say, shellsucks.com or wal-martsucks.com. Some companies really went far out of their way to purchase potentially unpleasant domain names: for example Xerox has purchased 20 unkind domain names, such as xeroxstinks.com, xeroxcorporationsucks.com and ihatexerox.net. 

These preemptive purchases could possibly lead to a lucrative new avenue for cyber-squatters to get involved in.
