Agreed, it was a mess-up. I see this commonly on some bans issued on other users. If you see something like this, feel free to change it to reflect a timed ban length-- keeping the ban reason the same. If their ban length exceeds that from when they were last banned, just unban them.
In this case, it seems mattin111 has served more time than needed, so once I get back online, I will unban him.
Make sure that you keep yourself out of trouble next time
