If a person reconnects with a reason "logged in from another location" there is no reason to broadcast them disconnecting. Same if they reconnect within a 3-6 second time period, as officially they didn't go anywhere. The ability to configure whether messages show up on these events would be nice.

Wouldn't you like to know if a player was offline when you try to /tp to them? No such player isn't a fun error to get, especially when you know that they didn't log off.

I'm not saying "don't show the message at all," that could easily be done by blanking out the field. What I'm suggesting is to avoid chat spam.

For example, remember when I had players that would have some weird bug where they'd connect to one world, and server-side it would show them reconnecting and switching worlds, all in the matter of half a second? I mean something that would stop something like that from showing up.
