Regarding VIP's ban (I couldn't see a way to add a comment on their appeal), I wanted to add my two cents - if that's acceptable. I don't believe the use of the F3 pie chart is explicitly banned or implied. It's vanilla functionality of the game, but a grey area for sure. A corollary would be breaking bedrock blocks, which while part of vanilla, is prohibited in the rules. My apologies if I've missed the PieRay note.
During my years on the server, several players have discussed the feature. Notably with mods/admins online at the time, who didn't interject. I'm a builder, not a base seeker, so have never really dabbled - but - my personal belief was this wasn't banned per se.
I think it'd be wonderful if the rules could be updated to include this. I'd also like to massively underscore I appreciate the admin and mod team that works to keep the server safe, inclusive, and free of individuals looking to seek advantages.
P.s. I don't know VIP, and I am again hugely thankful to the admin/mod team - not looking to upset anyone. Perhaps a rule clarification though would be good.
