First of all the guy i was running from i'm pretty sure he hacks,2nd of all if that bug is temp ban than just remove it or put some barrier blocks in there so nobody can use it,3rd u should fixed that "bug" so nobody can "abuse".In my opinion the guy also used that "bug" and i saw many many people use that but didn't get the ban but i did...You don't need to remove the ban i'll wait it out but in my opinion u should just fix it.
