It is pretty easy to see those out just commenting in hopes of a vote so I am not so sure I need to worry about them, There will I am sure be attempts by people to game the self vote comment vote, but they will be caught out.
A nice stable price of above $0.60 and I can give out comment votes with out running out of mana to soon, so I am hoping we will be staying above that now that we made it back through the first price dip when we hit almost a dollar.
