I've seen a few sigs from people saying that they will meta-moderate all negative moderations as unfair. This is an attitude I consider strange.
I will often meta-mod 'redundant' moderations as unfair, mainly because if someone posts something that is redundant, the mod points are better spent moderating UP something else.
Myself and many others are sick of seeing the same CRAP over and over again from the goatse, gnaa and other associated trolls that modding it offtopic is the only way to reduce the noise.
Sure, plenty of negative mods ARE unfair, but many are not. Meta-modding ALL negative mods as unfair just because they are negative mods is just as much an abuse of the system that these people claim that they are 'protecting'.
