"Vouch for viou" doesn't even begin to describe the level of trust that I placed in Viou. Needless to say I was not disappointed. Over a 5-day period, I sold Viou somewhere around $12,000 worth of rsgp, I sold him 2-3k worth a day, trusting that his bank transfers would begin arriving 5 days later. They did.
Tl;dr, went first to Viou for $12,000 of gold, all went well.
