Now in some outlier cases, bans have been reversed after a while to less restrictive punishments or none at all; in such situations are the evil points which were added removed automatically, or the have to decay as normal after a longer while?
A man commits murder and was arrested and taken to the law Court. The judge was able to establish his case that there was actually a murder case, but the murderer asked for mercy, by saying that he committed murder out of self defence. The judge considered him and discharged him. Will the case file of the murderer be removed automatically and disposed or will it be in the archive of the court?
Also, does signature ban or temporary ban affect the evil points?
Any student that disobeys the school authority would be dismissed. And if you are dismissed, you will not be admitted in the school again, or you will need to pay a fresh school fees. Then, Mr. Bayo disobeys the school authority, but instead of being dismissed he was lucky to get 1 month suspension. On returning in the next month, is he supposed to pay a new school fees?
