Japan's user number recently went down to 51. make that 50.
There is no reason taht only about 20 teams in japan actually anser emails, post in forums, have a pulse. 40 or so are training players.
Its not a small market. From where i sit as much as 50% of ALL accounts are multis.
So you are telling us that half your countries community are cheaters? I mean, I tend to be paranoid but thats out of my league.
Ask an NT-scout about contacting users and getting answers, if only 30% reply to your messages you hit the BB world record.
