When using Item Obliterator mod - https://www.curseforge.com/minecraft/mc-mods/item-obliterator
and placing items in its blacklist, their recipes are still visible in EMI (not occuring in JEI/REI but only EMI)
this may cause players to gather recipes on servers and then later find out they cant craft it.

emi-1.0.5+1.20.1+fabric.jar
Item_Obliterator-Fabric-MC1.20-1.3.0.jar

examples below

This would be an issue with ItemObliterator, it implements its plugins for other mods, there's nothing EMI can do from its side.

Ok thanks for responding so quickly, will get in touch with them
