This isnt the reason I'm leaving a bad review... but why do you have a loading message, plugins have that to show that no errors occured whilst loading it but your system isn't even a plugin and skript will tell you what errors occur whilst loading, or if it loads successfully.

I love how mutes, bans, and ipbans are permanent You check if every word contains the profanity, but what if i want to ban commonly used phrases such as `ass`?

Your chat listener also doesnt cancel plugins such as advancedchat and can not be turned off, so it's just an annoying additional module. (Same thing for chat filter)

Also, if you join and a player is vanished, you will see that player.

EssentialsX has better gamemode controls than your system.

I don't even want to see the inventorysee / inventory manager. Same for the player info module
