I think the problem is that with a fully refundable fee is that people will create bad securities and spam the system. But now there is no incentive for moderators to vote in a timely fashion so burnside is trying to make an incentive for them to do so (50% refund).
...and then they would just vote whatever to get the additional money. In other words, assets are now approved to give LTC Global voters more money. Would you say No or Abstain to an asset, knowing that it cost you personally to do so?
My answer to your question is yes. I have voted NO or ABSTAIN on 27 out of my 71 votes. I would not have voted differently if the money were refunded. I would still vote NO or ABSTAIN knowing that it will cost me money. I feel that in the long run, trying to maintain a level of quality of the assets on the exchange is worth more than the listing fee.
By the way, a person with 10 shares gets 0.1% of the listing fee, or about $0.50. I don't think the fee has much of an influence, especially considering that the person has at least $6000 invested in the exchange.
