For example, in the YoBit mass-ratings example above, ratings should be immediately removed after the person removes the signature, even if they maintain and continue to argue that they didn't do anything wrong. If someone agrees to "follow 'the law' without agreeing to it", that should be enough.
Which means that promoting scams is now an action that has a get-out-free card for negatives?
It was always like that, you tag someone because they are advertising scam, if they remove signature (or any other scam advertising material) - you remove your negative or change it to neutral.
At least that's how I was tagging and removing tags from scam promoters. I didn't remove negative from accounts who waited "too long" (if you know what I mean) to remove scam promotional material because I generally think they are high risk accounts, and if someone has been "neutralized" and they again choose to advertise another scam, that second tag I won't remove because user is just high risk. And, I removed few neutrals as well.
