The only way I can see it happening is if they honour 1 case and then basically be like anything after this you are on your own. This was mentioned by the Trust manager in a talk about buyers/sellers breaking policy where currently you arent told until stage 3 when you are either limited or kicked off, it will now be this is your first warning for breaking policy X, then you've broken another policy do it again and you are banned and then the obvious ban next time. If a buyer claims 2 or 3 times they've only received half their orders they get benefit of the doubt same with sellers but if it becomes  habit you dont get refunded and get banned.
