There wont be consequences/ban to the people that abused this? For example on EU Berserk guild has 2 chineses that sell mcoin with this method to members, they easily got full +10 as well. I can provide you screenshots on pm if you need them.
Years ago when a guy hacked gold on US server i remember you guys took away all gold gave away to random people.
Yup, for example Hassn always buy full price of normal mcoin and he felt pissed/scammed when found out few days ago how cheap people made guilds as strong as the one he owns. He has many business and travels china often, so if devs are okay with it it will be good news for F2P players. He can drop sign price to 2k if he wants
