I know microsoft is banning the ppl who leaked halo 4 but seeing as how ppl are getting random msgs on waypoint and xbl i believe it would be best to leave waypoint and stay off xbl and the internet for a few days til warfighter nxt week and wait it out staying free of spoilers.
Good bye. And if u want to be spoiler free i would try by not using the internt for awhile til halo 4 if need be so u dont get tempted at all which is the smartest thing u can do at this point and if u get random msgs from any one regardless of who it is just delete the msg/ tell em off if u want to and if they resend another message just block communications with em ull feel better trust me, blocking is the best especially to avoid spoilers
