Criticize Kevin Poulsen in a comment on Wired.com? That's a banning.

Kevin Poulsen posted an article that was plugging his new book, which I thought was pretty tacky. So I posted a comment critical of the article also mentioning that I thought he lacked journalistic integrity for his lack of objectivism concerning the whole Adrian Lamo/Bradley Manning debacle. Within an hour my comment was deleted and I was banned from posting comments on Wired.com. Has anyone else experienced anything similar? Is deleting comments you don't agree with a form of censorship or a websites right?
