There is a person who has such number of points that he should be at least Metal Demon or higher but he is Fred Durst instead.I cannot understand it. Is it only a joke or there is anything serious behind it.You surely know who is this person.

There is Fred Durst and Mallcore Kid. Both are from 0 to 0 points.
What is the main difference betwen that ?

The meaning is the same for all - you are banned, as it is explained in the rules.

He was allowed to keep his points as a symbol of his past work on the site, nothing more. And please, leave this issue be.

Every user starts as a mallcore kid with zero points and has to gain more to do substantial updates. It is a rank for newly registered user.

I just wonder how Christkiller got his Fred Durst status ? By himself ??

he sabotaged some band pages but I don't remember which.

No, that was not the case. It was because of things that mostly happened out of this forum during mod/user arguments or mod/mod confrontations and it also concerns certain reported items. Morrigan told on the general forum, what was the issue in brief, so you can find it there.

Please, leave it finally be, to bring it up constantly does not help anybody.
