Just a suggestion but maybe add a new record system where it shows all the bans and warns you've ever got.

For example on the profile card, it'll show this:

Warnings/Bans: 3

and when you click on it, you can scroll from top to bottom and it'll show all your warnings and bans like this:

Type: Ban
Reason: Harassing
Hours: 24

Its like a notifier for all the warns and bans you've got in the past. This could be helpful in most ways to the ban/warn system we currently have
