Shrinkage control. Anti-theft, externally energized, short range use. One of many designs.
Temporarily restricted can be years. My Twitter account has the same status. Going one its second month. "Unusual activity" is all I'm told, only on my profile page.
Restricted doesn't permit the user to login or use the account. My account is going on its second month of restricted due to unusual activity. No explanation from Twitter or means to appeal or reactivate the account.
The account is unusable while restricted. Can not login, appeal restriction or otherwise open the account. Read only to all persons, including the account holder.
Really. And they won't let user open a new account either.
