I understand that, but really it's looking at it in the wrong light.  If you are only planning on getting 168 coins, which is the prudent thing to do, then anything more than that is just gravy.  Why not just be grateful for an extremely generous gift and getting in on the ground floor of a coin that appears to have a bright future instead of worrying about other people?  It should come as no surprise that there are scumbags out there.  I don't mean this as a personal attack, but anybody seriously getting upset about receiving free coins because maybe some unscrupulous folks managed to game the system a bit seriously screams of an immature child whining "moooooooom, it's not fair Jimmy next door got two scoops of ice cream while I only got one".  Be happy you're eating ice cream while there are large populations of people that are starving.

Something else to consider is that even if some folks managed to scam and get some additional coins, it just means they're probably going to sell them as soon as they can and those of us who plan on holding can improve our positions on the cheap.
