So many deleted accounts

So I’ve noticed a trend. I’ll see some really amazing women or couples posting on Reddit and showing off or just sharing about an erotic topic, I might send a message and contribute to the conversation or share a thank you or some encouragement. Then before you know it, looking at the chat list, so many of them switch to “deleted account”. What’s the deal with that? Why do so many people create accounts, start to get some attention and then suddenly delete their account? I don’t get it. Have you ever done this? If so, tell me why or what happened?
