Why do some people on Facebook appear to be intimidated by your profile when you send them a friend request?

[Jeremy]

My Facebook account reflects high professionalism, extensive education, and love of travel and quality entertainment. I manage it well, understanding that a Facebook account is nowadays an important online public relations instrument.

There were several people that did not accept my friend request recently, although they don't seem to be very discerning about whom they accept -- it seems they accept friend requests from pretty much anyone.

So I thought about the possible reason for that, and the most probable one seems to be that they were intimidated by my profile.
It seems that most of their friends on Facebook are people they don't know.
