First off, that's a 2 day ban. They don't say 2 day ban because obviously when they issue a 48 day ban, by the time you login to the RuneScape forum, it is actually 47 hours 55 minutes hence they only call it 1 day because it is in fact 1 day, 23 hours and 55 minutes. It only tells you in terms of days, not in terms of hours and minutes. Also, the meter will stay at 50% I'm afraid. Best thing to do is appeal the ban.
