People saying pm me for support.

What issues are they going to be afraid to post on here?
Emotional support isn't usually directed towards one person, and no one is just going to pm someone at random spewing their guts out.

Let's say someone is confused about their sexuality, but don't want to risk someone who knows them irl or very well to know. So, they get help via PM from someone whom they can trust. Just one of many possible scenarios.
