<Snipped quote by Dinh AaronMk>

Given that it is a school computer, it is perhaps more likely that your school's firewall is not liking the Guild, probably for reasons tied to the Guild's content.

I would say it is more likely that it hates a specific element within the Guild's structure, and not the content. If it was, the Guild itself should be blocked, but if only an aspect within the site was blocked, then it could break the Guild client-side without completely locking him out.
