Let's see in reality how this works out. Maybe such cases shall be reported and recorded somewhere @sneak
Don't need to get hit by a truck to know what happens when you get put in front of it. There is a great big window for anyone who wants to be a dick to play .. doesn't take a genius to figure that out.
When not having a window, the system can be abused in a different way through self upvoted just before payout time. Not everything can be contained by software rules at the same time. My take is: lets try this. Lets report on abuse. When abuse is substantial, then try a different rule.
