How to mitigate or prevent lava casting?

What are ways to mitigate or prevent damage from lava casting and player’s ability to lava cast?

Lava casting someone’s base is one thing, but what if some players take it further and lava cast multiple biomes?

Also what are ways to eliminate any damage caused by lava casting?

Preferably through Vanilla methods or using well known plugins that are already out there.

You can slow down the water over lava spread speed. It will make it take forever for someone to make a lava cast they will end up giving up. You can even disable cobblestone/obsidian generators but that can affect other players.
