Imagine CraftyMynes, A server already known for griefing and raiding, has a regularly scheduled purge that will last for 6-12 real life hours. During that time, your guide book has been completely deactivated and you cannot use it to teleport anywhere. I think since players already keep their bases hidden, there should be a players coords in the player list when you hold down TAB. If you really want to get crazy with it, have the letter O, N, or E right by the name to show which dimension the target is at. You can't just simply hide during the Purge. Spawn will disable the saturation and resistance effects that you would normally get while there. I also thought of changing the function of the random teleporters to teleport someone to a random player in the world.
Now for my favorite part: Right before the purge starts, Bold, red, title text will show up in front of a player's screen. Using a custom resource pack, An EAS tone will play along with some (optional) eerie ambiance music. After the tones, a voice will say the following captioned [in chat] announcement:
"This is not a drill.
This is the CraftyMynes server automatically announcing the commencement of the regularly scheduled purge.
Normal rules for the server will still apply. You will still have to abide by them and disciplinary actions will be used if rules are not followed.
CraftyMyner and Admins have been granted immunity from the purge and cannot be harmed.
Commencing at the Siren, players will have their coordinates shown right next to their username in the player list. Your Guide book will have all features disabled. The spawn will lose the saturation and resistance effects that are normally activated, allowing players to kill others inside spawn. If you are a MVP, you will see a scoreboard showing the nearest player to you. Those with VIP+ or any higher donation ranking will have a scoreboard showing the nearest player to them.
Blessed be our dear CraftyMyner and all of CraftyMynes, a server reborn.
May the gods of CraftyMynes be with you all."
Right when this message ends, a siren plays in the background for a short time and a countdown is visible where the name of an object is displayed when the player selects an occupied spot in the hotbar.
The only reason why I made this conversation in the first place was because I thought it would be fun to just share my silly idea. Say what you want about it. I don't even care about this idea.
