I'm looking for a plugin for a minecraft server with which I can do the following:
Ban a player for about 90 days, or shorter or longer
So give a ban reason e.g. / ban hacking username
The plugin shouldn't automatically ban you
Spigot / bukkit
And is there a plugin that tells me which player is hacking?
There are AntiCheat plugins, but in most cases you have to ban yourself.
I just used essentials to do that, but there are a few extra things.
Anti cheat
Professional bans
or if you have bungeecord DK Bans
