Hm. Well, two of the boxes admins can check/uncheck when blocking are "Automatically block the last IP address used by this user, and any subsequent IP addresses they try to edit from" and "Prevent logged-in users from editing from this IP address."

So I would conclude from the second of those that IP addresses and accounts are connected. Typically, though, I only check the second one for serious violations, though I often check the first. If it was IP address and not username, though, I'm not sure why it would cause an issue with accounts. So in reply to your second question, the account should only be blocked if the second box is checked.

If you want to send me the IP/username of the person who got blocked, I can check their block log for the settings on their block.
