I'm pretty sure this will get loaded with anecdotes of "this one time, at band camp..." and "I always get it because I'm just that awesome" but it seems really uncommon for support players to get PotG - I've never seen it happen - and it's also pretty rare that they even come up to actually give the player an upvote. Seems a bit harsh, to the point that I'm now making a point of always giving them the upvote when I get the chance.
