ban lava?

there is a glitch on my server where people can place lava on claimed builds. is there a way to make it so lava is banned, or removed from people inventory

 

I think you should send this request to the developer of said land claim plugin.

 

There's also the plugin BanItem that does exactly that... https://poggit.pmmp.io/p/BanItem/2.3.3

 

I tried but the plugin didn’t load in
