My personal favorite is a guaranteed 50% refund if an issue hasn't received eight (

votes or been approved within a two week span of the start of voting. Refund too much and people will spam the system. Refund too little and the mods won't have as much incentive to vote.
Any other thoughts out there?
I'm puzzled, I thought that if you didn't get listed, you got back the whole sum.
It doesn't make much sense to pay in order to have the possibility of getting listed
or not.
0.1/5 BTC is the maximum amount I would consider "fine" to keep in case the security doesn't get listed...
There is a NON-REFUNDABLE FEE of 5 BTC per security created.
