The main thread on this is here:
https://bitcointalk.org/index.php?topic=312714.60There is no doubt Chadd is the man behind this scam. All the evidence is laid out in the above thread but here is the short version:
The SAI admin account had the same avatar Chad uses here for a short while. Also metadata inside pics posted by SAI had geographic data pointing to Chadd's hometown in the UK.
At first Chadd denied this and said he emailed SAI about why they were using his profile pic (which miraculously removed minutes later). Then a dating site profile was found with the name Scott Daverno and it had another pic of Chadd. It is also discovered the SAI website has the same IP address as Chadd's ShitCoin called Extremecoin. The SAI domain and ExtremeShitCoin domains contain the exact same contact info.
At this point Chadd makes up a story that he met the SAI guy Scott at a bar/pub and they asked him to build and host their website. And that he signed an NDA agreement and can't reveal identities. Because you know most reputable tech companies are incapable of creating websites and have to hide behind NDAs.
He continues to say he was "just hosting the website". A few days ago a twitter post from SAI says "we would like to say goodbye to Capt Chadd who is no longer hosting out site to work on ExtremelyShittyCoin. Totally normal for a company to make a post like this announcing a very basic web hosting change right? And how convenient that Chadd is leaving how because anyone following this scam knows that SAI is about to drop the big bomb of shit and disappear.
Right now Chadd is admitting to hosting this scam website and is the only human link to this scam. I don't think anyone believes he just happened to be in a bar one day and was asked by a fake company making a fake product that doesn't exist to host their website.
Let's get this fucker. Before the SAI forums disappeared a couple days ago the SAI admin (Chadd) was mocking people who wanted to bring legal action saying "good luck explaining to police what crypto stocks is" and "bitcoin isn't even a real currency so nothing was stolen". Not only is he scamming people he is now talking shit to the victims.
