TWC Request / Vouch-Whoring thedudo

Link to scammer's Sythe profile: http://www.sythe.org/members/315431-thedudo.html
Briefly explain the trade: He said he was selling 30m 07 gold. I told him I'd buy it. Then he refused to sell me 30m and instead offered 2m and then later 2.5m to "see if I was legit." I'm almost positive he's just vouch-whoring but is stupid enough not to realize that ten 2m vouches <<< a 30m vouch from someone who has a decent amount of trust.

Not TWC worthy, he just wants quantity instead of quality.
