how would u find my blog if there was no signature here?

By going from this:

)
But honestly the complaint is mostly the nature of signatures since ad campaigns, and not really signatures in general; but if signature campaigns aren't really policed (should it get even worse), then removing signatures in general would be the idea.
Seems unlikely to happen, so blocker script it is; doesn't take care of nonsense posts, but at least removes some of the eyesores.
