Thanks for the answers guys!
I will use the traitorfinder, but sometimes it is buggy. When a new round starts sometimes it shows still the items from last round.
I don't want to support any other hacks, but a while ago (1-2 years) I found a hack which did the thing what I wanted. (Changing the colors after a traitor bought an Item.) And you could filter other players so that you use aimbot only for your enemys. (But now you get banned if you use it)
Would be amaizing if the hacker crew could add that feature. + Is there a way to support the crew?
