Does this MAF Sensor look normal?

I am no MAF expert.

1) Is it definitely broken or is that what the inside of the unit actually looks like new, I have nothing to compare this to.

2) If it is broken, what might have happened to cause that and how can I prevent it from happening to the new one.

I might be wrong, but isn't that the purpose of this tech forum? To learn from other people's experiences.
