The hack presents a way for the owner of a site I visit, but did not give any other consent to whatsoever, connect that page visit to my LinkedIn profile (which is, basically, me). And then uses that to contact me.

This goes a lot further than an ad broker that knows I am the person that visited sites X,Y and Z and therefore probably have an interest in something (without, still, knowing really who I am).

I know Facebook (and the likes) could technically know where I've been, but I have no clue on whether they really do that, is there proof for that? And is that really accepted? And even then, it's a step further because Facebook at least knows who I am because I 'willfully' told them and chose to 'trust' them.
