DisableMessageDeletion

Since 1.19, the server has the ability to remove player chat messages on your client, as long as it has a valid message signature. 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.

Messages with a prevented deletion within that deletion delay period attempt will receive a purple indicator on the left of the message.

Example

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.
