Facebook sued by Lamebook

After Facebook suing Teachbook and Placebook, it is now being sued itself by Lamebook.
Lamebook is a website which mocks Facebook about funny comments, photos... people post on the most popular social-network website of the moment. Facebook is being sued about trademark infringment.
It is true that Lamebook has a very similar logo and look. Facebook complained about this and already threatened to sue Lamebook in March but they never did and Lamebook never changed.
Although Lamebook looks a little like Facebook, it doesn't have the same purpose. On Lamebook, you can't start a social network. You can only post funny comments, found on the Facebook website. It is in fact just a parody.
Facebook is afraid that the website is an improper attempt to trade off of Facebook's popularity and fame. In my eyes, this isn't how it goes. I think that when people see Lamebook, they will get curious about Facebook. It is true that Facebook is made fun of and I do understand they don't like this part but I can't see Lamebook as a real threat. I have to admit that some parts of the Facebook website are a little bit ridiculous but it has its good qualities too and everyone who wants to critisize it should have seen this side too in my opinion.
When Facebook sued Placebook, it resolved in Placebook changing its name. It is normal that you can't copy a concept and you can't just copy a layout but Facebook is very well known and I don't think they have to be afraid about competition. Placebook also refers to Facebook but it is more about places then people.
I don't think that Lamebook will win. Facebook was first so I can't see how they are being sued due to trademark infringement. Facebook has gotten very big and is still growing. I don't think Lamebook will cause problems.
