stop day dreaming, thousands of players buy / sell gold on daily bases and no one is getting banned.
and yes i know alot of people buying gold…none of them got any ban because blizzard would never ban those valuable customers, they are the main audience as future (classic) token buyers.
People have been finding ways to solo content through various unorthodox strategies since this game released almost 20 years ago. It stands to reason people will use those strategies, in addition to ones recently discovered, to make gold by carrying people. It is part of the game, plain and simple. Blizzard has implemented various changes to prevent people from going overboard with it, but there is absolutely nothing wrong with boosting.
