I doubt this time it's a hack, but I do know the Steve has had the site down before.
I am not sure what account suspended means in this case. The payment could have lapsed, or he exceeded his bandwidth for the month. Somebody could have complained about something, and he could have been shut down pending an investigation. (Guilty til proven innocent.)
Unfortunately this is all speculation since we don't have any information.
Regardless, I do, and will continue to support Steve. TVF has helped so many people over the years that we should be able to handle a little glitch in the system.
