Btw, I just checked, and they have reappeared on LinkedIn.: ~snip~
But what could it mean? I have no idea.
AFAIK, Sorsis has never disappeared from LinkedIn. When were you unable to find his LinkedIn profile? What I have seen is, his LinkedIn 'followers' and 'connections' have increased since the downtime of Betnomi website. However, their official LinkedIn profile has been deleted at the end of July month.
