@Skillroad. All you need is a post count of at least 10 and have joined before the start of the IPO. Sure there will still be some that are prepared sockpuppets but it would get rid of 90% of them. You delaying this simple action makes me and others im sure wonder if you are happy to just take in sockpuppets. Don't forget the coin was supposed to be against the unfair nature of NXT. If you get one or two guys with 30+ stakes with less than 1000 total you will have some big stakeholders just like NXT.
90% of them were created for Nem IPO, so restriction by registration date won't help. Probably closing the IPO right now would be the best decision. There's working beta which totally proofs that the coin is not a scam. Hundreds of scammers will jump on board now.
