Minetime Updates - October 15th, 2020. Global - Epic & Timeless players now have access to /nick - which allows users to change their name. Please keep in mind, that abusing this with offensive language can result in a ban. Global - AntiCheat updates. Improved a few things. Ended up reverting the changes we made to flight hacks, we do need to improve this some more so flying around at the speed of light isn't fully allowed.
You can't take usernames of other people that already exist on the server. But yeah, players could still change up the name slightly, it falls under staff impersonation though so players can get muted/banned for it.
