I just got on my Xbox to try and figure out what it could be and when I tried typing in my name as the title of a map it made it Blam! Apparently my name is blocked by 343's filter. That just makes me wonder how I can even use war games.

I'm not banned and haven't used my file share before today. I guess I'll try contacting someone. Thanks for the help.

When I try to upload my own maps to my file share I get the message: the creator of this map is banned from xbl and it doesn't upload. I can upload other people's files but not my own. If anyone knows why this is please help.
