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.
Sorsis disappeared from LinkedIn about the same time. Or, at least it was like that to me. I had been checking all Betnomi related info once a week, and it was a good news for me that Sorsis reappeared on LinkedIn. Also, seeing this today

instead of this scary message

that we had been seeing for quite a while, is a relief for me.
I would not like to say it is a good signal and there is a chance for people to recover their balance, because I am not even close to be sure what in God's name is going on, specially on the LinkedIn going off and on.
A scammer would just delete everything they can while exiting the scam and never turn around. Perhaps some change of heart because of the fear of the possible legal consequences all this mess could have on those whose personal info is available on internet?
