I built (by following tutorials, see below) a Mob Grinder. It's a simple 20x20, with water, etc.
But when I go up there, it's not dark inside. I don't use Gammabright and I didn't put torches or anything.
I went to have dinner and put hoppers in the ground and stood 1 block away from the spawner, to see if some mob spawn and falls. But I got just 5 bones, 2 strings, 1 gunpowder and 4 rotten flesh, which is far less spawns than in the video.
I'm playing on multiplayer, but I'm very far away from other players. I saw in other topics, that we need to stop the mob spawning in the area around me, then they will get more chances to spawn in my trap, but it doesn't works, I don't know what to do!
When I'm on the top of the spawner, the Y is 96, and when I'm on the ground, the Y is 65. By the way, I think the problem isn't the nether rack, 'cause I see on the gamepedia, and it says: "Usage: Netherrack can be used as part of a trapping mechanism for Mob farming."

You need to be 24 blocks away from the spawner for mobs to spawn. Also, if you're within 128 blocks of the ground and haven't lit the caves up, most of the mobs will spawn in the caves. Either AFK 128 blocks from the ground or light up some caves. Make sure you're within 128 blocks of the landing pad for the mobs though.
Another thing, when there are other players on, the mob cap is split between all players in 1.7 versions and below. If you are playing in 1.8 snapshots, that doesn't apply.
As far as it being bright in there, you need to make sure it's all closed off when you're inside to see if it's dark. If it's still bright, try hitting F3+A to reload the chunks and see if that updates the lighting.

Why does my mob farm does not work?
Check to see whether it's complete darkness inside the mob spawner or not. 0 means no light's coming through. If the light level is at 8 or higher, mobs will stop spawning.If Your Mob Grinder Isn't Working, Watch This!
