I find it a bit strange too. Maybe a lot of people think it is a dating site and leave when they see it is only a forum. Others are trolls there for a quick poke. Others leave if they are upset. Some the younger ones find it a bit racy.
Let me tell you why, we all like to believe we are individuals, but we all live similar situations. It gets super creepy crazy to see people talk about what we think only We are living. It awakens like a narcissism in some so you get paranoid and start to think your being targeted. Its ridiculous of course happens to me all the time. But I'm completely bananas
