"on tab complete" doesn't block the `/` command.
You also did not specify if it was SkBee or SkQuery, so i don't know which addon you wish us to use.

This is also NOT bungee-spigot, it's Skript, I don't know how you think people can use this on their bungeecord proxy (thats what the `bungee-` prefix implies)

Also the on tab complete blocker will absolutely flood your chat.

Mods like Meteor still can get your server plugins.

If you want an actually good plugin blocker and not this, go to: https://www.spigotmc.org/resources/regex-command-blocker-universal.99589/

even if it requires regex knowledge, it does add everything this does, but better

Nice skript! I like it because it can solved my problen! Thanks for you! And I can aslo use ABPS to solved.
