The sales have been okay and payment was sent in 7 days, so that's good. But is Subyshare based in Japan? Given that a majority of the content is Japanese, it's seems likely that there may be big issues sooner rather than later.
I've had little sales, but those are just a side-effect of sharing. Even if I was after sales I wouldn't get much because others that are truly after sales quickly scoop up the titles I post and turn around with links to other hosts like Rapidgator, Uploadable, Uploaded, and others, so that would take away from suby downloads right away. And can you believe these fine individuals never say thanks. Must be nice.
