Are kicks/bans by key or account?

[Professor]

When you get banned from a server because some moron just ran out in front of your tank, is it your CD-key that is banned or your player account (or both)? If it's just the key, I may consider picking up a second copy and creating a .reg file so I can quickly rejoin (as I used to with BF42).

Thanks

Bans are usually player ID or player IP I thought. Nothing to do with CD key?

I would think player ID.

IP makes no sense, because most people's IP's are dynamic. In 1942, it was the CD-key hash that was banned... change your key and you are back in the game. But with this new accounts system, I wonder if it's different.
