They do it to every console. One guy microwaves the consoles he buys, with money people have donated to him for that purpose. I think it's dumb, but it's the internet after all.
A lot of people do dumb things on the internet. 
It's such a terrible waste of money, and it does kinda take consoles away from the people who really want to buy them to play them. Launch stocks do tend to be limited, after all. I'd be irked if I wanted to buy a PS4 but the stores were out of stock, and I saw someone blowing one up on the internet for laughs.
Amazon put up some bundles to buy for people who didn't pre-order one, bought me the Killzone one as soon as I saw it.
Expected to have it in the next 2-3 weeks!!!!!!
2-3 weeks! Well, at least you'll get your console before Christmas. 
The PS4 does have a lot going for it, but I'll wait and see how things go over the next year or so. I'm pretty happy with PC gaming, and I did also buy a Wii U for the family and Nintendo games earlier this year.
