The two rules that were broken were stated to be C2.4 (Combat storing) and G4.4 (When you are downed: [...]). However, I believe there was a minor error in that I did not perform any act of Combat storing, rather it was Combat logging, which is C2.3.
C2.3 - Combat logging
This rule was broken as I exited the game after being downed for a small amount of time as I became slightly frustrated.
Quitting the game or leaving the server while roleplaying is a form of cheating, as it can be abused in order to either gain some sort of advantage in the game or save your own time at the cost of other users' roleplay experience. In my case, this was a form of rage-quitting. However, other cases of combat logging could include leaving while in a gunfight that the user may not want to engage in or may feel they would lose, being chased or arrested by police or while being detained, or perhaps exiting the game so that others cannot loot the user's gear. The user is always supposed to re-join the server and continue roleplay if they do happen to logout.
This rule is critical in order to achieve a positive and immersive roleplay experience for all parties, even in unfavoured scenarios for some parties. Everyone needs to have their turn at being the one who may win a fight, successfully catch and arrest a criminal, or loot someone they may have killed, and if the victim were to leave the game in all these situations, there would be no satisfaction for the other player, and their experience will be ruined. If this act were common, people would be discouraged from playing the game, as there would be no risk in performing any uncertain activity and the excitement and realism would soon die. It is one of the most important rules in the game for people to not combat log, and continue roleplay as normal in every scenario, no matter how negative it may be, as this is what makes the game so eventful and interesting for all players. This is essential for achieving a positive experience for everyone.
G4.4 (When you are downed: [...])
This rule was broken in the same instance, as I was shot in the head in-game and continued to speak fluently without attempting to roleplay my injuries whatsoever.
Users are required to roleplay their injuries, meaning if they are downed in the game, they must change the way they speak and act accordingly, using their character's voice and other communicative means to represent as accurately as possible the condition they are in. Being downed is not the same as being killed, which happens when a player respawns, therefore users should still be able to use their character's voice and not act as if they are dead. Additionally, users must not make any mention of the respawn timer in-game, since this breaks immersion and would not count as roleplaying.
This rule is important for creating an immersive experience for other players involved in the vicinity of an incident in which you are downed. Roleplaying injuries accurately, perhaps even referring to the cause of injury, or body part(s) affected, and level of pain or general medical condition helps make the game more real for everyone, and enhances the roleplaying experience, since it creates more opportunity for interaction, involvement and understanding of the situation for surrounding players. If this rule were absent, and not all downed players acted as injured accordingly, it will likely ruin other players' experiences, by creating confusing scenarios in which a player who may be downed may act as though they are fine, breaking the immersion for everyone else, or similarly perhaps either claiming they are dead, which would not be true, or speaking about the respawn timer, which would break everyone else's immersion.
Overall, both the rules that were broken seem to be very crucial to ensuring everyone has a positive roleplaying experience, and it is evident how breaching either of them in any way would impact and ruin the game for everyone else involved. They must be followed if the game is to continue to be what it deserves to be, another immersive world for players to escape in and be a completely different character to their real life self! The goal should always be to make it fun for everyone, and have empathy in situations which may not be entirely enjoyable by accepting the events and roleplaying like everyone else.
