Currently a player can vote in a poll from 5 mins after they join a league. I propose that we increase the buffer time to multiple days (preferably 3).
It's useless to allow people that are likely to eventually become inactive to vote, with this feature the people who vote are far more likely to be people who will continue to be relevant to the league long after their decision. This would also greatly reduce the spamming of votes through joining with multiple teams to sway the poll in a player's favour.
There's no poll more useless and unfair than a fixed one however slight it may be, so this would be a feature that would positively affect most if not all future polls.
