Certainly, I just don't think you can say all cases should be handled with the heaviest punishment at hand - meaning they were of "bad quality". Using HGPs own words "don't judge so quickly".
I am not here to say anyone is wrong, I usually don't even post at all, I just think it is worth the time considering if this Murloc guys intentions was purely to harm the server, and regarding the fact he already now have felt some punishment, wouldn't make him think twice before breaking any rules again?
No one but Murloc himself can assure he won't break any rules again, but I believe second chances can do wonders.
I merely wanted you to reconsider before closing the case, it is your server and therefore your call in the end.
