It's a forum, it's used to talk and give his opinion on something, or just having fun.
And you are all complaining because of useless posts that gives points ?
Well, you just play for the competition of having points in that case, if you were a bit more mature than this
you would not care about this system, and just use a forum as it should be used.
Don't complain about short useless or private joke post, we need everything to do a great forum.
But of course yes, an hour system is better, I saw this on a forum, even more like a 30min than a 1h would be such perfect
