Let's make everything clear with what happened this night.
Xndo and I are paying for a Minecraft server and setting it up so all of you can have fun.
He asked me for help to set up permissions. He said that he wanted Officers to have some permissions but not all of them (no OP or gamemode 1 for example).
So I joined the server and started to work on permissions. He told me to close the server to do work, but I thought it was better to let play the 8-10 players that were online.

I should really have closed the server: After de-opping all players so they could have correct permissions that I set up, I started to get insulted by some players (not to mention, mostly ReallyMadHobo).
And that's pretty much it, during all night people were spamming, insulting, complaining about anything, while I was fixing what Xndo asked me to do.
So yes, I banned at most 3 of the players for 15-30 minutes, because they were spamming, insulting me and generally causing trouble while I was trying to work. To make it short, I did what an admin should do.
I am not a "corrupt admin" like some of the players said, I'm also owning the Minecraft server and I only did what Xndo asked me to do.

So tomorrow, the server map will be reset after the vote we've made on the Discord.
And some players will no longer have access to the Minecraft server for obvious reasons.
Thanks to all that are playing without being toxic.
