bbstats seems like it USES bbapi but I don't think it's officially run by BB
so bbstats probably doesn't know if/when bbapi is ever coming back
he asks for donations to cover time spent on development and webhosting I assume, if BBAPI gets shut down it will be on the graces of that gentleman who runs it to return money if appropriate
In case you don't know, BBAPI is a set of "programmer tools" that coders can use to access certain information on the BB servers. The guy who runs BBStats isn't officially affiliated with BB, you see. So he doesn't know any more than you about when it will be fixed.
