No, why?
I suppose that although most have a professional social network, I suppose, that like most people, they will not want any undesirable to be able to get into their social network, for example to insult them or mess with them.
Unfortunately, here in Spain, we have had several cases of women journalists, who have had problems with their professional networks and with undesirables who entered their social networks.
But removing that fact, these girls have a professional life, to give an example, which is active and that nowadays, can be seen on social networks.
