About Apocalypse venues?

Hi, 

I have a little question about apocalypse venues, this few month they grow up all around the world and I didn't find official information about it? 

Here some example: 
http://www.foursquare.com/quixado/lis... 
http://www.foursquare.com/v/4sqapocal... 

Most of the time the cat is totally absurd! 

What is the statut about that? As regular user of 4sq, can I do a legitimate check in ?
