I requested my notes from a mod, and I can go through explaining any of the particular ones you have issues with.
The 'metarush' note was not a meta rush, in my view. I was the XO on LV with minimal staff in the CIC. I decided to try something new by having the marines deploy to LZ1, set up in the cargo domes, and then set up a secondary FOB across/on the river. The IOs were going to scout the colony with some volunteers from other squads.
What happened instead is that someone stole a megaphone, shouted "BRIEFING IS OVER" before I could even finish giving all the orders, and then all the marines rushed over onto the dropship, deployed, and proceeded to unga across the river the moment the fog dropped. The xenos also had next to no defenses, so the marines had almost nothing stopping them from rushing.
There are no other notes for 'metarushing' as far as I know.
I have one note for a 18+ joke I made as RO when someone was griefing me for refusing to give them something, he tried to buckshot me and I somehow didn't die from it, so I made a stupid joke that was consistent with how my character acts. The discord ban is something else entirely, which is resolved now. There are no other notes for 18+ stuff as far as I know.
My understanding of the expectations of the server and staff has changed, but I am consistent in my views that few things can be claimed to be 'LRP' as long as there is no actual definition for what LRP is. My character's personality is consistent across multiple rounds of gameplay, he's a guy who was effectively raised on movies and Old Earth media, so he acts like a weirdo and says dumb stuff. However, I can understand that is odd even by CM standards, so it can cause some confusion when I claim that it makes total sense for my character to behave oddly.
Overall, I am the same person I always have been, I just understand that certain things are expected of the server, and I work around/with those expectations. I will still have and voice my opinions on how I don't believe that "LRP" is something that exists on a server that is effectively a TDM server. The job of the CO, as I say in my app, is to make the round fun while remaining in-character. As long as the character's personality is consistent and their behavior doesn't break OOC rules, I think anything short of rule breaking is fine.
The large amount of community support should also help show that I am not a 'problem player', I am just a guy who wants to try and make the server a more enjoyable place in my own sort of way. Yes, it is different and weird compared to how some people play, but I think it is overall a lot of fun and everyone has a good time when they get to interact with me. That's the main reason I want to get the CO whitelist, to make the server more enjoyable for everyone on both the xeno and marine side.
