CreeperKiller is a mod that originally only removed ads produced by the CreeperHost mod, it's become clear however that it has potential to block any ads in minecraft menus. Currently it blocks the CreeperHost mod's main menu ads, as well as main menu mods introduced in HammerCore. if there's any annoyances similar to these then notify me and I will attempt to add a new blocker.
Also, if you're taking this mod at all seriously you're making a horrible mistake.
Don't take this too seriously, it's a mod that disables the creeperhost mods main functionality, adding things to guis that don't need to be there.
Q1: Couldn't I just remove the creeperhost mod?
A1: Yes, but that's not nearly as fun is it?
Q2: How does it work?
A2: After the creeperhost mod loads, creeperkiller will find any event handlers with the mod id "creeperhost". Once they're gathered it will unregister them from the forge event bus.
Note: This is in no way affiliated with CreeperHost or the modpacks that use the CreeperHost mod.
