When the free version came out I played (with Prime) and one of my haxxer teammates said to me that there are 3 other hackers in the match. Is it still like this?

I think, its way better what it was before the free version. The cheaters are playing in non prime, and the VACnet is verry effective. There are some cheaters left in prime, but the game is more playable.

Vacnet is getting a little better and I haven't seen a cheater in prime for a while now

I think it is not too bad as it looks like

Of course yes, The game will always have cheaters

I think the ammount of cheaters has been reduced with the game being free to play

Probably you can see some. But cheaters are less

yes i can see that everyday

they is but i dont know

Bettter, then without it)

Better than not prime

well not really because prime is paid soo even if there are cheaters they wont cheat if they cheat they will get banned and lose the money they spent on prime soo it is very rare in prime ..
there are some rich cheaters tho lol

You won't have many cheaters with prime actually very few but you can still get smurfs griefers and stuff like that
