how we can play like that?

Z8 can only ban the hacks with the evidence provided by the consumers who play Cf. Therefore if you don't report the hackers they'll stay here.

Also another thing, this is a f2p fps game. No matter what f2p game you're going to play, there is going to be hacks.

I report tons of hacks, almost every day I report some, so many I'm tired of reporting. My Support Contact History has 7 pages already of Hacking Report, only in this account. And thats because I only report when I'm 100% sure its a hack. Guess what happens, I keep seeing the same hacks for weeks, I submit multiple Replays of the same sometimes, and they never get banned, or just lose their ribbon and get back to hacking.

This one for instance http://clan.z8games.com/charstat_cf.aspx?usn=3576808

If his team is losing and the round is about to end, he turns on his aimbot that one-shot kill everyone through walls. And the ***** is free and online right now.
