Maybe PRP manager would allow it, but I'd never do it on SWRP.
Warns are deterrent as everyone knows they are permanent, if they go away then every ones mentality about them changes. We have forgiveness, we allow appeals. If the warn isnt false, own up to your mistake.
Somone will simply say, "Well idk if i get warned cause it will be gone in 2 months so I can just rack up 20 warns and they'll be gone soon."
