Registered for a ".tk" domain name

I had register this blog to a .tk domain name, which is:

www.shiphire.tk

But there is no way to remove its banner, which is kinda a nuisance.
Is there a legal way to remove it?
Is removing it through html code legal?

You still could visit this blog normally though
www.shiphiredustbin.blogspot.com though.

Please inform me if there is a way to remove it though html codings.
