I sincerely doubt it's the poker sites themselves that are writing crawlers to spam blogs. The sites ask for a lot of trust on the part of their users, and losing that trust would kill their business. More likely, poker site Affiliates, who make tons of money for referring new users, have more incentive (and less scruples) when it comes to doing something like that.
Oops... sorry. I guess others have already pointed this out. Don't often read below a score of 4. ;-)
