Well, rule 1 (admin discretion I assume you refer to) exists for situations where something happened and where rules would technically have to be enforced (or at the contrary, rules cannot be enforced) but the admin makes a decision to not (or to actually do) enforce them or remove any punishment over the player due to the situation actually going a bit deeper rather than just “unga broke rule, ban he”.
The situation I’d use as an example would be the report against Owen where he valided a sec officer who was a dick to him since the arrivals shuttle on MRP, where yeah, Owen did kill a Sec Officer on a MRP round, which by MRP standards is overescalation, but the guy was (or as Caec interpreted) ban baiting him, hence flexing the rule to exempt Owen from a punishment.
It can also be enforced in many more ocassions such as toeing the line multiple times, or people literally being the type of player that both players and admins don’t like dealing with, ICly or OOCly.
So if an admin enforced the Rule 1 against you (or anyone really), then this means one out of two options
Either A) He’s a cunt and literally only him hates you, and you may create an admin report since anyone who flexes Rule 1 is responsible for it
Or B) You’re the twat and the admin actually took it to the Headmins/Seniormins first in order to get approval, after seeing such a negative reaction from a big fat fucking chunk of the playerbase. Literally your presence is deemed a problem.
Keep in mind this is literally a fucking rare event since usually those type of people redeem themselves (The biggest example I can think of is @OwenMcShain since a lot of the admins back in 2019, myself included, were kinda annoyed at him and his playstyle) or just move to another server before getting to that point (I still miss Grogovic).
So yeah, tl;dr Rule 1 should probably stay since it’s the way admins can do stuff that the rules would not allow them to do for the betterment of the playerbase and the server.
