there is some words on most servers: - U payed for the account, its up too you too take care of it and its your own fault if u are banned from the favorite server if the friend did it during a sharing/test/loan moment.- cant remember the correct sentence but u get the picture i hope =)
i belive even Scawen-Victor-(insert correct name here of the last freak in the crew) said this somewhere on lfsforums about acc share online.
just my 2cents
btw he pm´d and said: a friend played and he didnt check it was correct driving etc ??
where was the owner then ? even if its OFFLINE testing for a friend i dont leave the room 1sec while he is driving.
