Hey, thanks for the respond.
The fact that without itemku there will still be RMT is not a good justification for a company to capitalize from something illegal. This is very similar to saying that it’s ok to create a drugs trade website (Silk Road) since without that website drugs trade will happen anyway.
The reason why game company doesn’t want RMT is because it reduce their profit. A company like Itemku that supports RMT will in no way be able to cooperate with this company without starting from scratch with a new business model.
