lol, "What happens to people who buy gold?
Players who choose to buy gold and support these exploitive companies may find the purchased gold removed from their account so that it can be returned to the rightful character. If it was your gold, wouldn’t you want it back?". Ya that'll make everything better customer pays for gold-> Customer receives gold -> Blizzard Steals gold from customer.
As far as the threat part goes:
"What is Blizzard doing to help?
Our developers, support staff, and anti-hack teams work diligently to stop the exploits these companies use and help players who have become victims of their operations. We're constantly evolving our techniques to detect and prevent the latest risks players face to make sure that your characters are available when you want them.
We've also added more convenient and fun ways for players to acquire the funds needed to play, such as daily quests, guild perks, and XP to gold conversion at max level. These opportunities are available to make sure that players can focus on the types of gameplay they love most, without needing to grind for hours to cover costs."
If they had a way to complete their task we wouldn't be here right now. same scare/threat tactics they always use to scare people and give them the false impression they're on top of their game.
