My characters deleted

My characters on Lordaeron, Icecrown and Outland deleted? I can't restore them? Or need to get into the game? Sorry I don't know where to write about it

did you check just on website?
In that case they might have been flagged for a rename due to inactivity. In this case you need to log in game to set a new name (or the previous one if noone has taken it)

Btw, nice avatar.

Oh, yes, thank you. I need check it
