No, with Admin-permission you can give people drive-through and stop&go penalties. If this is done in last 2 or 3 laps, you get a time penalty.
So, I doubt it was a bug, maybe you either crashed someone in lap1, turn 1 or whenever, you werent liked, the admin went nuts or and admin was playin a prank on you. Still, no nice move, to not even explain, why you got that.
