Your enforcement differences refer to the text filters, is that right? The text filters mainly deal with web addresses, but then, even JP web addresses are in english, so that really makes not much difference. There hasn't been a major crackdown on gilbuyers so far, so all avenues are equally safe so far.
I called NA/EU players who buy gil incompetent, and I will stick to that. I will also call ALL gilbuyers of ANY race incompetent. This is one generalisation I will make.
