Maybe I LIKE to see them (I don't particularly). But who are you to decide for me what I want to see?
Just go into your profile and set "Don't show users' signatures." to on, that's simple...
I see a 'Ignore Boards' link... maybe if there was an 'ignore users' link I could just add people that (so rudely) use giant signature images.
i like to see people's signatures, just not the in-your-face ones.
