Your appeal boils down to the following points:
1. I stopped when asked.
2. It's not harassment because I stopped when asked.
3. It's not harassment because freedom of speech lets me accuse him of being a pedophile for no reason
There's no acknowledgment of wrong doing, no acknowledgment that accusing people of shit like that is not chill, etc etc.
Point 1 and 2 are contested by multiple staff members who say you continued despite being told to stop, you argued with JMZ and continued after the fact despite claiming you instantly listened as well as arguing in the second sit (refusing to comprehend your actions, a consistent theme)
You don't seem to grasp the severity of making baseless accusation, yes as a one time joke these comments are whatever, but to continuously, after being told to stop, try to besmirch someone simply because you don't like them or you think they might not like you is irresponsible as hell. Anyone can claim anything but without actual proof you're just hurling baseless libel, which obviously isn't "Freedom of Speech".
This isn't the first time you've gone out of your way to harass people you have issues with, I have seen the way you behave in personal messages with people, your overall attitude isn't very much different than a spoiled rich child. I've seen you crash out about when being made to leave factions or for getting pk'ed. You have on multiple occasions professed your 'hatred' of persons in the community and claimed you could easily go find them, maybe to harm them, etc. Harassing or other factions on alternate characters, you have already been reported for this poor behaviour and I wanted to see if this was a one time crash out or indicative of a repeated pattern of schizophrenia.
Ultimately this proves it, I liken your behaviour to that of a child. It's a video game server, you get too invested, too emotional, you ascribe issues in roleplay to that individual's character as a person and bring the beef OOC constantly. It's embarrassing.
I think the permanent ban here is appropriate, if this harassment of Riggs was the only issue with you I honestly would not mind reducing the ban, but based on your inability to take responsibility, the other past threats and harassments, concentrated efforts to damage factions on alt chars and the very suspicious arrests you were making on your PD char I think Boomroasted's decision to extend this to a permanent ban is more than justified.
I don't know how old you are or why you behave the way you do but I think you need a serious period of self reflection, not only to realize what you did was wrong and why but to actually fundamentally change who you are as a person, because as it stands it does not seem enjoyable to be around you. Consider this an intervention.
You may re-appeal this ban in a few months.
Incase you don't understand why I am denying this appeal ATM, read here:
I think your have a problem with your anger and emotions, I think you lash out verbally when things do not go your way, in RP, related to staff, in DMs, regarding money. I think it's immature and a negative trait and to allow you to continue to behave this way is damaging for the people you interact with and your own well being.
