This is a very important point. I just read through the rules on the PBP website. It seems that anyone drafting someone not in the race could receive a 1 hour time penalty.
I expect this is more to prevent the fast guys breaking away from the front group and then having a buddy up the road waiting to give them a draft. I expect that this rule will not be applied to anyone who isn't going for a fast time since there will always be wheels of registered riders that they could follow if they wished, so I wouldn't be giving anyone an unfair advantage. However, it would be better not to test that theory.
