As for bar, please don't make yourself look silly providing really weak and easily countered excuses you come up with off the top of your head. There is nothing to "game". A customer could not order and claim to or they could order and claim they never got the product. OH NOES ordering stuff can be gamed I guess KNC will stop selling products. KNC deals with the "risk" of being gamed on orders but can't on RMA.
If I recall correctly, the 'game' that KnC was supposed to be avoiding was this: Say you have a Saturn, and want to upgrade it to a Jupiter. You could complain to KnC that both the boards in your Saturn are underperforming to the point that they deserve a replacement (or are just broken). They ship you two replacement boards immediately after you send your "security payment". Then you just keep the boards, thereby bypassing any queue waiting on upgrades (or avoid the total nonexistence of such, as of this writing).
I am not trying to justify KnC's RMA practices - I feel sure they ought to be able to find a way to work around this 'gaming'... I'm just pointing out what I think the game is that they are trying to avoid.
