If the sock puppets were clever and greedy enough to signup for multiple stakes, then they will do the same in the NEM waiting list.

The new people wanting to join NEM should have additional requirements. Only those that will be beneficial to the NEM community should be offered a full stake. This may not be practical, but here is my thoughts.

Keep a majority of the refunded NEM stakes in escrow. Once the waiting list is closed, for a full buy-in price they can join NEM. By default, they will each receive 1/10th of a stake. If they join the NEM facebook page, they will receive another 10% of a stake. To receive the remaining 80% of a stake, they will need to demonstrate how they helped promote NEM in some way, such as posting a NEM article on a major social platform, donating their NEM, introducing others to NEM, etc. They will have 6 months to do something for NEM, afterwards they forfeit their claim and the remaining NEM will be donated to our development and marketing funds. This should motivate them.

Also, we should set aside several stakes, later to be given to influential people and individuals that are highly connected, like ones with popular blogs/websites/youtube channels.
