I agree with everything SkriptingPanda said. Also your reply to there message made no since and yea this skript sucks. Aswell as you said "it blocks commands fine", they never said it didn't. If anyone is on drugs it you

This is legit the worst command blocker, why did you even make a resource thats just command blocking its so easy and this is very inneficient, dont use this..

That's a great plugin! The plugin allows to block the messages of commands that you don't want your players to know about, if it says info about the server or if it's an admin command that lets the players know about a plugin. This specific plugin prevents plugin thieves from stealing plugins from your server.
Also, for me, the plugin works much better at 1.8.8 Spigot.
