For the spray exploit use silvers fix
Silvers took care of that long time ago.
And as always I would advice to install vote manager, that will disable bugkick/forcekick/glitch kick etc
If you don't wanna do that you can disable sm_status and other commands that show the players ID. There was another one showing the ID but I forgot which one. Oh wait listplayers was it. Might wanna block spec_goto also.
Or Block votes during connect
Prevent players to create the double tank exploit.
On servers with unlimited team switch, you can create a large number of infected bots.
On special spots, you can cause instant death of survivors by spawning infected on deadly places, both fixed here.
To prevent trolling with water jumps, you can disable the jump swimming glitch.
For some cheats you might wanna try anticvarcheat
And ofc lilac
Hope that helps.
