I like to know the personal live about the streamers that I care about the most, after all, we are all people and people get interest in other peoples lives when they find the other person interesting, even not being sexual.
Some streamers I have then added in personal media profiles, some of then I talk to in calls, some call me their friend and I never donated a single sub in my life, literally because I cant. It is just a connection that you end up building with people and I created with some streamers during years being there and I am sure that a lot of people did the same. Just saying that is not necessary "lonely individuals that obsess over their personal lives", people just like other people.
STPeach, one of the biggest girls in the world, married her viewer, so everything is possible.
