The true fact is, one always gets to know; who is, or who is not, genuine. Who will, or who will not, offer some glimmer of genuine support, undertanding, insight, and/or signposting. Who is genuinely selfless, or, who has an 'all about me and my needs' approach to people. Who is, and who is not, dependent on the words of praise to fill an inner empty void. Who does, and does not, responds with envy, or, from a perception of lack of attention. Who is, and who is not, needy. Who has, and who has not, an apparent inner purpose and contentment.
Then there is the disordered person, who behaves in a disordered way, which you get to know, and see.
What You See Is What You Get.
It's the same all world over, in real life, and, in a supportive community environment - cyber or none.
It's simply, a fact of life.
