Thing is, it's not a problem on jp servers at all. I've been on tonberry 10 months and can't remember ever getting one. I watch my bf play on typhon and he never gets them either.
Fact is, jp players don't tend to buy gil, so there is no market. Part of the reason name servers have these shouts is because people buy!
Of course se should do more. But the number of players who buy is a real problem too.
