I'll just go through some of your points one by one:
"I threw a incendiary grenade right at the beginning of the pre-round towards, the water on minecraft city." If the fire had been in the water I wouldn't have been hurt by it.
"Addi purposefully walked into the fire then reported me after the round had finished." I was bhopping around and ended up passing through flames, there's nothing intentional about that.
"I profusely apologized as I was just trying to test out the new rolls of timing and elasticity on my grenade." The first time you did it you responded to the report with a joke, and then did it again a few rounds later after being told not to, so at this point it doesn't matter that you apologized for the second one.
"He did not accept my apology and chose to try (and succeed) to get me banned approximately 10 rounds later." Yes, it takes time to get bans finalized.
"Addi was the only one to go into the fire as it was far from spawn" "Screenshot included down below also indicates players walked into the fire multiple seconds AFTER it had been thrown which indicates it was purposeful." Like I said, when you're bhopping and someone throws fire everywhere you're bound to pass through it. That's why you're not supposed to throw grenades randomly as an innocent or during preparing.
"Addi has frequently expressed he does not like me" I didn't know who you were until this week and my opinion on you was more or less neutral until 2 days ago when you sent me a video on discord of a woman starting to undress, when you started PMing me in game semi-ghosty things to do while I was alive and you were dead, and when I started seeing how often you called people "retard". The first and only time I actually expressed that I didn't like you was this afternoon when I said you were annoying me.
" and earlier said he wanted to "get rid of me"" Actually, what I said was "Why are you trying so hard to get yourself removed?" as a response to you intentionally trying to bother me. That's not an indication that I wanted you gone, just me saying that your behavior was unacceptable.
Anyway, it doesn't matter that you didn't actually kill anyone with the grenades because you were told after the first time you threw a grenade randomly during preparing that you can't do that but you did it again anyway, and that shows your intent to cause trouble.
