If you want to stick with the spirit of Blockchain and encourage an evenly distributed format, then mining is not the way to go. It only favors early adopters and those who can afford to mine this coin. Rather, I would suggest that you disqualify newbies and also maybe disqualify jr members accts that was created after a set date to eliminate farmed accts from the next airdrop. A simple script can also detect and eliminate cheaters with multiple accts.
 By the way, i understand the reasoning for letting the cheater keep the coins (i don't agree with it) but one rotten egg shouldn't fuck it up for everyone else[/b]
