WotLK Question about a BUG...

Dont know how many times i must ask just some GM to tell ?

First:
I made a report on 25 december, about this thing: https://www.youtube.com/watch?v=ePxX006Dzjo
The report was for that players "Vasquezz", becouse as u see i show with "/who" to see which DKs are in Storm Peaks. There are two DKs.
On the second part of the video (5 mins after the first part), you will see that the Death Knigh player Vasquezz is not in Storm Peaks, and then nothing gets the mobs...
Ussually the GMs awnser on the reports, but still no awnser...

Second:
I made a topic in the forum to ask is this some cheat or some bug.
One member wrote that this is a phase bug.

Third:
I also made one ticket in the game when i saw in one day many different classes (maybe and different players) to kills on that way.
The awnser was to report that bug in the bugtracker.

Fourth:
I am trying to report in the bugtracker, but when i choose expansion Wrath of the lich king, its shows me only character from the Lordareon realm (its under 10 lvl), so i cant make the report.
I tried to make the exapnsion Wrath of the lich king(OLD), but then when i choose category it says "That category does not exist for expansion Wrath of the Lich King (OLD)."

So what now ? If there are no any bans for using some bugs like this, please some of the warmane staff to tell here...
