I used to run GDKP Raids in ICC/DS with no issues and great success.
Everyone wins, you get gold if you don't get items. Everyone is more motivated, better than a standard PUG. Good way to gear Alts.
I came back to WoW after about 5 months away and the last month has been kinda boring for my alts. LFR is zzzzzz. So I thought I would start a GDKP

Have a full raid but the thread got locked and look at what the moderator posted ;/
GDKP Raids not allowed anymore?
UPDATE FROM A GM TICKET

Hello there,
This is Isolatius from the Game Master department here at Blizzard Entertainment. Thank you for taking the time to contact us. You have been correctly informed the GDKP runs are unsupported transactions and are discouraged.
This change in stance went into place nearly 2 years ago.
The reasoning was that while there were many legitimate runs, a large percentage or runs ended in a scam or dispute of some sort on how the gold should be split.
Also, in many cases the buyers would end up buying gold beforehand which became a real mess when it was uncovered that the gold had been acquired by the gold selling company in a compromise. Explaining to "carriers" that we had to take back their gold that they had earned in the run due to it having come from a compromised account was a real mess and wasn't a situation we wanted others to be in going forward
These days, we treat these runs much like in-game "casinos" which is to say that if people engage in this activity, and everyone goes away happy, we don't really mind, but if there is some sort of dispute, it can lead to account suspension for the hosting player. We will also not reimburse any sort of losses that occur.
It is worth noting, that simply advertising a casino is a serious violation and can result in account action just for advertising. GDKP raids aren't at that same level, but are otherwise pretty much in the same boat.
Hopefully that helps give you some background on the situation. I was working these kind of reports back when the change was made, and I can assure you that things were out-of-control when this stance change went into effect.
Please let us know if you have further questions or concerns about this
Also, on a side note, we do NOT allow bots, and regularly ban tens of thousands of botters. If you happen to suspect a player of botting, please let us know using the in-game reporting option.
Also, its worth noting the vast majoirty of botting is done on compromised accounts by gold selling companies. Some of their most noticeably activity includes the "teleport hack miners". If you see any of these, please let us know as soon as possible so we can secure the account and get it back to the owner.
We appreciate your time and understanding in this matter. Please feel free to contact us if you require any further assistance. We hope you continue to enjoy your experience in World of Warcraft!
