GoDaddy is the largest registrar, and anyone can use their anonymyzation. So 'checking other sites' and THEN seeing that some anonymous someone registered via GoDaddy provides little negative evidence against GoDaddy.
I agree. You couldn't go to court with this type of evidence, but you have to admit that for the site to be available, then within minutes of you searching for it on GoDaddy, it then becoming anonymously registered would raise eyebrows.
But that scenario -- searching only through GoDaddy (preferably HTTPS), and seeing that domain gone minutes later -- is not described in the comment I responded to. Nor in the parent linked article. Nor was it in the prior report this article mentions.
And yet, even if that did happen, GoDaddy gets millions of registrations per year, and many times that in lookups. So losing a domain minutes later is certain to happen many times per year for strictly innocent/coincidental reasons.
And some of the advice being given in these sorts of threads -- use DNS/whois lookups, use other random website services -- could be increasing the risk. (Those protocols are eavesdroppable, those services have less to risk than GoDaddy.)
