How to stop players from going into the Nether?
I'm making an adventure map and players should not be allowed in the Nether.
There's a few things you have to understand:
- Players have access to Flint and Steel.
- Players can make a Nether portal by using a water and a lava bucket.
- Players can go as far as they want, the map is endless so command blocks won't be effective when players walk too far.

The answer is pretty easy even if you don't want just to fill the while nether with air.
Use "Client consent to play fair". Basically it's that you prohibit going to the nether in the map rules and players must respect it.
Or use command blocks:
You will have to place and power this repeat command block right under the spawn to be always active. Put this inside:
/execute @a ~ ~ ~ fill ~+1 ~+1 ~+1 ~-1 ~-1 ~-1 minecraft:air 0 replace minecraft:nether_portal
You can fiddle with the numbers a bit for the best result. If your world gets laggy, you can use a clock and a normal command block instead, or adding a command block with testforblock.
