I understand that you can tell who's voting, and I'm more worried about my followers in this scenario then myself..

The situation I was trying to avoid goes like this:

• One of my followers finds your post and votes option A
• I come along much later and vote option B
• They then vote-follow and vote option B invalidating their bet completely

See what I mean ?

• Under your system I would need to always vote immediately or not at all, and have my followers know they have to change their votes later or they end up just donating voting power with no prize even if they chose correctly immediately..

• However If you only count the first vote registered, and people with trails promise to say only vote on an option after ~18hrs then nobody ever has to have their vote invalidated :)
