In my experience blizzard are shit for catching people.I had a 5 man dungeon team running but was only making around 400g/h and around 600gph for the looters so I didn't think it was that great for making gold so I decided to make my own way of gold farming and I have been doing that for over a week now and have made around 150 euro.I'm just waiting for my mop accounts to get banned so I can start fresh with better classes( tip *don't make hunters druids are the best for gold farming trust me*)
I would not making a 5 man dungeon team not because it's risky or that blizzard have a way of catching the people who have the botting teams because blizzard don't. 70% of bans are based off of player reports.
If you are interested in a way of farming gold pm me and I will let you know some good ways. I don't want to publicly post about they ways so they don't get over used
