I have a suggestion:
when players change to killing mode (red name) and have the behavior of attacking other players, they should be restricted to change mode again after a certain time (such as 12 hours), so as to prevent some disgusting players, these players temporarily change to attacking mode after meeting other players who can be killed, and immediately change back after killing them, which is very unfair and annoying.
The principle is: if you like to kill, you can, but you must stay in the red name for a period of time as a constraint,should not like this: change to red name when you want to kill, and pretend to be peaceful when you don't want to kill.
