I'm an admin on the F.E.A.R. wiki, and a user recently left a message on my page claiming that the site was hacked and they were blocked for a short period of time. I suspect the problem is really that wikia went down again for awhile, and that this user's poor English made it difficult for them to understand the error message they were getting. I doubt they got a worldwide ban, since those are generally permanent, AFAIK. There's no record of this person being blocked (or anyone being blocked since late February), so I have no idea what they're talking about.
