Considering you were warned for the exact same thing and were stupid enough to continue led you into this mess.
The fact that you're intentionally breaking rules to raid a base (and impacting the RP of countless people in the base) AFTER being warned a few seconds prior led to "extreme" measures being taken to teach you to follow the rules; as clearly you didn't give 2 fucks about the warning(s).
Losing the item itself is not really the reason why. It's more the way i lost it, if it got lost during a raid or something like that it would have been a completely diffrent story. And tbfh i would have learned more from the admin giving me a few days ban then a slay. Cuz now i know when i want to propclimb to just take off my suit and i am good to go.
Sadly for you a warning didn't teach you shit so this was the next best option, fair enough he could of banned you for a day or two but what difference would that of made to your mentality; you broke the rules after being told not to so in all honesty with your current attitude you'll be getting warned a hell of a lot more.
