I agree that disrespecting an admin 13 times is insane. Also I think that for someone that has already disrespected an admin they should have a ban that shows them not to do it again. Therefore I think that a max ban of 2 hours for a first time offender of disrespect along with the spam is reasonable. Therefore it is important to note that he preformed this action 12 times after the initial outburst. (at a very fast interval i know)

Thus it is 2 hours x 12 outbursts = 1day ban. He will be unbanned tomorrow.
