This plugin allows you to prevent cheaters from using Fly on your server. Recommended for Anarchy Survival servers. You can enable or disable it from the desired world via the config file.

config.yml

dontflyworlds:

• Arena
• world
• lobby

#names of the worlds where fly needs to be disabled

no-perm-message: "&cYou don't have permission to execute that command!"

reload-message: "&aConfiguration reloaded!"

When you install the plugin, cheaters who try to fly will fall directly to the ground, meaning they won't be able to fly. Of course, those with operator privileges can fly.
