Are the portal 2 dlc links real or fake ?

I havent been keeping an eye on portal 2 but m8 just mentioned the dlc was out. . lots of new mltiplayer maps etc.. has it actually been released ?, see alot of threads and alot of d/l links.. suspiciously like 7 gig per links.. seeing alot of repitition.. but people that i trust like tooth dont have the dlc ?.. is it available, is it a flood, should i click report abuse on every single one ? hehe
