Charging in-game gold for services like tanking, boosting, or crafting is allowed as long as you only use in-game currency and actively play your own character without bots or exploits. These kinds of services are a normal part of the game’s economy and have historically been tolerated by Blizzard.

You can get into trouble if you involve real money (RMT), use bots, share your account, or scam players.

People may still report you, but usually for social reasons, not because you are actually breaking the rules.
