This mod allows you to disable the server's ability to retroactively remove messages on the client.
By default, the minimum amount of seconds to pass before a message can be deleted is 10 seconds. By
installing modmenu
and cloth config, you can change the delay, or completely
disable message deletion by setting it to -1.
Here, the minimum delay is set to 5 seconds. If a deletion attempt is made before that, the message in question gets a purple indicator. Only after the delay has passed, the server can actually delete the message.
