With sincere respect to Danny's efforts, he is attempting to win a game of whack-a-mole, which history and logic warn against. I wish him well on his war against the moles, but consider it a distinctly Sisyphean task - and more to the point, it shouldn't be necessary. (He also apparently shitcans people for other, more subjective transgressions, such as profanity, which leads to the amusing possibility that, were I to adopt his list, I'd be unable to see my own posts.)

In any case, it's a heavy-handed, all-or-nothing approach to treating a complex symptom, when there's such a simple way of tackling the cause. Nobody needs ad signatures, they communicate nothing of any merit, and it's evident beyond any reasonable doubt that the quality of posting on the forum would be improved by their absence. I just don't understand why the glaringly obvious solution continues to be ignored.
