They're within their rights to remove someone's access from a site that is hosted by them - that is, to remove their access to the GSI servers and the website. However, Gamespy does not own a single piece of content on the websites hosted by them, as stated in their own hosting agreement. They do NOT have the right to modify the content of hosted sites UNLESS it pertains to a security risk on their part. I suggest you read the full thread linked to in that email, as I left a lot of the details out in order to keep the mail short. The fact is, they broke things on purpose, modified what wasn't theirs with no right to do so(there was NO security risk), and then, they LIED about it.
