How do I check if I have been temporarily restricted?

Can I check in my online blizzard account anywhere if my diablo 2 lod account has been temporarily restricted by any means? Or does a Blizzard staff member have to do this? I’m trying to figure out why I can’t log onto my d2 lod battle.net account since I haven’t been notified via email about anything. And it was working fine a week ago before I reinstalled the game after reformatting my pc.
