Vouch posts are spam
There is nothing to discuss about that

Then why should people even bother getting them? Just make a spam thread and spam there instead.
Vouch is defined as "To give personal assurances; give a guarantee."(http://www.thefreedictionary.com/vouch)
If you're going to bother 'vouching' someone, even for a +1/spam, you should be prepared to be held to the same standards as the item seller himself/herself if something goes wrong with the trade, including replacing lost funds due to scam/"item poofing"/etc.
If all it amounts to from a moderation point of view is spam, and people don't appear to be getting warned enough to stop this type of spam, why not implement a "trader feedback" system to eliminate the need for the "vouch spam." Other trading forums have done it, for diablo 2 as well as other games, so it's not impossible. And it wouldn't have to replace the Trusted tag, either.
