Hi - banning admin here
Unfortunately you had gone offline by the time I was ready to pull and speak with you, I apologize.
Your ban is the product of a variety of clips and pieces of evidence shared with me by the TM, in conjunction with your extensive history of notes, including 4 bans.
No active threat is made to you in the duration of your interaction with the TM. As can be seen in the linked clip, you did not pull your weapon until you had seen the TM begin to holster his, at which point you shoot him. - https://outplayed.tv/garrys-mod/mEjMDJ
You have also been seen to harass and bait at the property across different chars, with a consistent group of at least one other player. https://outplayed.tv/garrys-mod/B5yzJv
Here is you pictured with said player on the char who was involved in this current issue: (I believe the image is corrupted here, I will reupload it if strictly necessary)
The TM had known you by name and had also made complaints of harassment and potential metagame via referencing his IC name in an IC channel, on a character you do not have his f3.
Overall, the clear cut RDM with a serious history of notes is what has landed you with a 10 day ban, which seems more than generous looking at your overall record, and history of short bans despite it.
Hope this explains my thought process, and good luck on your appeal
