I'd like to request a feature that expands punishAlts and customizes its behavior. Instead of banning the alts, I'd like the ability to simply denies login with a message that says something like, "The IP you are joining from is linked to a banned player."

The idea is that we can prevent players from simply rejoining on a new account after being banned, but not necessarily ban any account attempting to join with an IP that matches a banned player.

That would be great.

Perhaps denyAlts in the config would suffice instead to cover this use case?

Nice 👍
