A while back I went in on a KNC Titan group by done by Waldo.  It's been a while since this group buy and I don't know what he's done since then.

But in my experiences, Waldo is trustworthy.  He kept us fairly updated on the status of the Titans, even with all the delays.  When he finally received them he got them set up and starting mining.  The weekly payments were always on time.  He told us the Titans were mining on cex.io.  When I received my payments I did some basic blockchain crawling and saw that the coins were indeed from cex.io and were only 1 hop away from being minted.  It was obvious that he was actually mining and not just another ponzi scheme scammer.

The Titan deal ended up being a terrible deal, but at no fault of Waldo's (in fact, he did all he could to help us recover as much BTC as possible).  He kept the miners running as well as he could, and even managed to sell the Titans for some decent money.  He said we would receive our fair share of the money from the sale of the Titans.  I did the math to figure out what my fair share would have been, and about a day later Waldo sent me nearly that exact amount.  His payout matched my independent math, so I knew he was being fair.

A bit later I was in a Teamspeak server and someone was posting pictures of their old Titan mining setup.  It wasn't until after looking at the pictures I noticed the user's name was WHDHJ.  After that I realized it was actually Waldo.  It was kind of amazing that he coincidentally proved again that had actually mined and did what he said he would with everyone's money.

So I have no doubts about Waldo's legitimacy in the past.  He had done several successful group buys before mine.  He did my group buy as expected.  For these reasons, I won't be removing my positive reputation.  My experiences with him have all been positive.

From a few minutes skimming this thread, it seems like chalkboard17 simply got himself in over his head.  He wasn't able to provide proper documentation to receive the shipment, and now is expecting the seller to pay him back more than he originally paid.  Waldo made it clear to us that his bookkeeping was done in USD, and that's how you would be refunded.  Expecting different is just silly.

I also have concerns about this because chalkboard17 seems to be relying on emotions rather than objective and logical reasoning.  I don't care if you have a baby and a wife.  Posting a picture of a baby isn't going to alter my opinion.  I base my opinion on verifiable facts, and chalkboard17 just seems to have trouble providing consistent facts.

Regardless, I hope this situation can get worked out and both sides can be satisfied with the outcome.  Waldo is being communicative, so I see no reason to get out the pitchforks.
