First of all, everyone who has nothing to do with a specific ban/unban request please stay out of it.

It doesn't matter who and why you insult, if other people break the rules it doesn't give you the right to do it. In this case you told the admins to "stfu" and you were being provocative towards the admins, therefore the ban and the length is fine as it's not the first, nor second but third time you do it.
As stated above, the ban stays.
