Then make a topic dumbass.
What's the problem here? I can't really see it.
Just because the topic is in the top of the list doesn't mean you have to click it.
If this dude likes to share his experience about mattnett1 he could do it in this topic just as he could start a new one.
It really doesn't bother you at all and certainly doesn't make him a dumbass for bumping this.
