Is or was?? The thread was started with that exact username.
I think they just mean they can't play on that account. I think there have been a few that have posted on accounts they can't play on.
The pic and equipment would be there but if they can't be found in search then they've been banned. I'm not sure what anyone is supposed to do, all their play seems to have been mobile so is hidden.
From their wall it does seem that someone was looking for, and had trouble finding, them. Obviously didn't know the username.
