Which anti-cheats can I turn off?
From MTA’s anti-cheat guide. Turn one off only if it wrongly blocks your players, for example because of a mod your server allows.Which special detections can I turn on?
Special detections block things that aren’t cheats as such but that some servers don’t want.
Special detections can lock out honest players, for example 28 blocks everyone who plays through Wine on Linux. Add them one at a time.
Should I allow custom skins?
Allow custom skins has two options: No and Peds. Peds lets players join with locally modified player skins ingta3.img. The panel notes it is not for competitive servers.
