You have been banned in the past for both teamkilling and teamwounding, so there's less reason to be lenient with ban duration. "Anyone else" gets their case taken into consideration just like you did before we determine the length of the punishment, should there be any.
If he, too, was causing trouble, the proper course of action is to report problems, not exacerbate them. Try using to-admin chat ('i' key) or taking a screenshot and posting your own request next time, please.
Your ban has ended by the time of this post.
