tbh, i think the early nip were pretty clean, and after more and more teams got in the cs go pro scene the cheats came with them, remember 2013/2014 theire were some teams and you nearly knowed all of them and on every major everything was pretty clear, recently there are hundreds of new "pro" players out of of nothing and so many teams and these new guys, allot of them are cheating im sure.. thats a reason that NIP has became so bad in my opinion..
