Grogan:It would be nice if MS could implement black lists in a future update.
But as much as I like open systems I 100% agree that devs shouldn't have this kind of power. Or maybe the could if they are trusted MS partners/OEMs.
Or if they..in any way they wont go through the certification process if they are spammers(in layman lingo).
Even though,they may not be MS Partners or OEMs.
