Just to add to my point before, also about only removing 1 point at a time, by the time they have been found they would have gained their survival bonuses anway so they make a 'profit' that round regardless should they care about ranks so I think you would have to make it a higher detriment and that would only piss people off. I know that if it is just me and 1 or 2 other close friends on a server, we just mess around and the hider or hunter usually ends up killing themselves for LOLs, is it really fair to penalise them as well as though being annoying?
On another note, is this really a huge issue? It happens to me maybe once every two weeks. Every week would be lying as it isn't consistent. Overall, does it really matter?
My solution for hunters is to pop the flare before running blatantly in their direction, that way at least you get the 'finished off'.
