WotLK Deleted Characters

[badboybs]

I was inactive for several years, and I guess my characters got removed because of inactivity. Is there any chance at least some of them to get recovered / restored ? Realm is Icecrown.

Characters level 50 and under were removed. All other inactive characters had their names removed. Log in game and give new names to your characters.
Or maybe someone logged in, sold/deleted your characters(check your account history), secure your account.
