Taken straight from the Rules section in the Wiki:

I have seen posts from the mods saying the area that the mobs are spawned in must be at least 10x10.

 

That's what I understand as well. I am trying to find the post that said it needs to be a 10x10 room. I would just build a small 1x4 hall off the spawn room and wait for them to build up. Place 1 block on the floor at the entrance of the hall so they cannot damage you/come down the hall(unless its a skele spawner, then you would need to modify this). Break the block once they build up, then go in and kill them. Go back into hall, place block on the floor to entrance, let them build up, kill them. Rinse and repeat.

 

if you are requesting a ban appeal. post it in the ban appeals and complaints section

 

Can we make them fall a few blocks THEN kill the mobs? Like I mean, it doesnt kill the mobs by itself.

 

It cannot damage them. If they fall and don't get damaged, then by all means sure i suppose.

 

You also can't transport the mobs in any way, so I'm not sure how you would make them fall without moving them. Just stick to the hallway off the main spawn room and you won't be penalized for it.

 

That's random...wrong thread?

 

From a recent ban appeal:

 

sure wish things like this were thoroughly explained in the rules. now after about an hour searching the forums i think i understand what is legal.

 

The needing to be able to move freely in a 10x10 area is not part of the rules against mobs traps and should not be worried about.

 

That makes alll dungeons illegal..... alll dungeons are 9x9x9 lol

 

The 10 by 10 bit was just made up be one of the mods. I have stopped xp farming for this reason.

The rule is too undefined. I wouldn't even bother xp farming it's not worth a possible 25k fine.

 

Its not "made up". Its up to the mods to enforce the rules. And mob traps are a gray area since there are so many possible types of traps that can be made. Its not as black and white as a no griefing rule is. I feel childers was merely trying to suggest a way to xp farm and be safe from getting in trouble. Just play by the rules and this won't even be an issue. I have personally hit level 50 multiple times without making a mob trap. Just take the damage, heal up and keep going.

 

They shouldn't be adding rules all willy nilly though.

 

It might be helpful if someone (and this could be anyone who knows what they are talking about) would post a thread where it is easy to find describing what is legal. maybe giving a few specific examples. this might actually prevent some new people from building something and getting banned making it easier on the mods and letting them focus on other things.
