It's not illegal to talk about a trademark or collect information about it, and present that. A newspaper article talking about a bunch of negative blogposts and tweets about a brand is not infringement, and Squidoo isn't much different.

It's illegal to try to pass yourself off as someone affiliated with or endorsed by someone when that's not the case by using their trademark. The five instances of the word "unofficial" all displayed prominently above the fold on the Squidoo pages should take care of that.
