In reply to the OP from years ago, but still a relevant question: IIRC some of the relatively recent Russian spying was facilitated by fake accounts/people being linked on LinkedIn to real, high profile people. Simply being linked lends some false legitimacy, so now other people may trust the fake account, which seems to be from a real, well connected business person. I don’t remember the exact details, so whoever has the time can to their own research and post here.
Bottom line answer, yes be wary.
