Besides the link what other proof do you have that it is a hoax..
How are the getting so many different voices?
How are the getting the sirens in the back ground?
How are the recreating all the other ambeint sound around them?
You offer one flimsy specious claim that it is fake based on the webspace it is being run and linked off of.... How about a little more proof before you make any more assumptions like that.
I think your argument that it is a hoax is weak at best.
but the IP adress is the same and that means it is comming from the same location. (unless they are hosting the feed) and I doubt a bunch of emo kids would do that.
