I wouldn't worry too much about it. They claim to be investors. The one whose question I tried my best to provide with a quality answer says he was surfing for trolls, and now is gone. Of course, if anything like another we used to deal with who was always leaving but never really did, he'll be back anyway. Hopefully in peace. Strange things happen in the absence of press releases. No coincidence.
