Trust has literally nothing at all to do with moderation. Let's leave it at that. They are independent of each other and have completely different systems.
Would it make it any better if you were to be given negative trust by Vod, for example?
Trust is given at the user's discretion and should not be affected by the rules of the forum.
If you are making this argument then you too should know that scams aren't moderated and are technically legal by the forum's rules. Does that mean that it would be wrong for a mod to tag someone red because they aren't breaking forum rules?
