I'm glad that this trend didn't reach Austria, because as annoying as it may seem, swatting can result in deaths of innocents, if the cops are trigger happy or the victim fears that (possibly armed) robbers are breaking into his/her home.

This kind of hoax should be punished harshly, even for 15-17 year old juveniles.

What punishment do you recommend?

[fixermark]

Something up to and excluding the punishment equivalent for negligent homicide.

... and that restriction only to avoid the calculus where the punishments are equivalent, so someone getting their jollies by ordering armed responders to an innocent person's house might as well go drop rocks from the local overpass instead.

Why ask? This is why we have a judicial system. It may be (very) unfair in some cases, but for the most part they are there to dole out appropriate punishment.

Ten years of community service. :)
