To be honest, i found it fishy too but i think QI was just lazy and was not keeping track of the competition when it exactly ended at 8 PM GMT, I kept track and i know for sure Alew was in the lead but since the post took like a day to come out to reveal the winner, they probably waited a bit longer, which allowed Meh to win since he kept campaigning. They for sure need to have much more stricter rules and keep to them if they do something similar in the future, because if they did end when they said they would end at 8 pm GMT, Alew would have won by a few votes.
Edit: Atleast by eyes alew should have won, just saw the post about QI using the SQL to track the votes. That makes sense but it also makes it kinda fishier lol
