Since it was posted on youtube and he has 64k subscribers then it won't take long for it to get fixed, since it disturbs the economy. Have fun while it lasts.
If you don't want to see his quick video of what you have to do then here's a TL;DW:
1. Queue up for Dragon soul LFR by talking to the lady outside of the raid entrance.
2. Kill and loot the elementals before first boss. (You can kill boss if you want since it's LFR.)
3. Rinse and repeat.
A group of 2 elementals and 2 cultists drops 40g+ and there's about what 10 groups of mobs? So 400g+ per run and it takes 1-3 mins depending on your speed.
