It has been stated on xboxdotcom if your found to be hosting modded xp lobbys you WILL get a permaban and possibly a console ban.
You can risk it from such replies as 'nah',but thats just his opinion-im telling you what was officially posted by M$ employees.
People who have obtained prestige illegitimately, will be given suspensions. People soliciting other people to gain prestige (whether for free, or for points) will be permanently suspended.
No doubt you will point out that doesnt say a console ban,but as some hosters have already been console banned is it really worth the risk?
Im not going to start CnP stuff,just take my word for it.
