Yes. But they've already said they won't say why. 'Posing a risk of generating invalid activity' is the closest they came. It's a form letter, though. They say that to everyone to cover themselves. I have appealed. I'll see what happens next. Apparently, sometimes spam bots can access your pages. I guess this happened to one of my blogs, so all the other accounts are held suspect. There's not much you can do but appeal and wait. I'm trying to be positive about it and hope that they'll realise I did nothing wrong.
