This account must be removed from the forum or we must all give a red trust so that his account equals 0.
While I agree with first part of your sentence (yes, the forum will be better without the village idiot), unfortunately, there is no reason for giving him red trust.
Remember, this is a
Marketplace Trust system, and positive and negative tags should be given only for financial deals, not for trolling or being an imbecile.
Negative (shown as
-1)
- If you believe someone is a scammer, or someone is likely to scam, that deserves negative feedback. Please provide evidence.
- If you really hate someone and he's a terrible troll, that does not deserve negative feedback.
However, a neutral feedback can be left for various matters. If you are curious, check the neutral feedback I left him (and you'll be amused to see that it's identical with the neutral feedback icopress also gave him

).
So in this situation -- of imbecility taken to a hole new level -- only a neutral feedback is appropriate.
