The reason why people joined in the first place is irrelevant. The only thing that matters is how and why they leave. Most don't join to scam, but many leave doing so.
I joined for the blackmarket services/gold, my god, it's cheaper to work, and then pay someone else to do it for me. I always knew they existed in the back of my mind, but I just never truly trusted them lol.
I joined to trade an account for personal use. Then I became addicted and started trading accounts for non-personal purposes. I may as well try to do MM.
I'm not gonna lie.. I joined with big plans I'd like to sell my accounts and then do free botting services (looking for a partner atm) and then once I get a fair ammount of vouches, start a paying skill training service = P.
