Is multiaccounting banable?

I was on kit pvp and used a 2nd account to gain Exp since Idc the kills or coins or whatever, I was curious to find out what rank comes after got well and I almost have it 3742/4000 so 258 to go is this forbidden? Since ive never bought a kit (and i wont do) and i never fought other people instead of my second account? Im just asking if this is against the rules. if yes. Ill stop it. (I got dragged to ask, this was not my own decision)

Yes it is.

Kay. good to know finaly
