As for suggestions that we are in some way untoward because we have not shared our personal linkedin profiles, well I must reject that entirely. Apart from our right to privacy, if we were behaving as you suggest then it would be a relatively trivial matter to create a set of fake linkedin profiles. I am sure that you have seen the kind of thing I refer to - and in fact some fake profiles can as you know be very convincing. In fact, fake profiles seem to be the very first thing that dubious operations like to implement!!
