I hate being ghosted 👻

I feel it often.
Its one thing not to get answers on my first messages due to the warning on my profile, I may understand that.
But its worse to convince people to chat with me though, explaining to them my warning, chatting with them for a while, and suddenly they stop answering without an understandable reason. As if I suddenly have gotten online leprosy or something. 😞

How can people be so cruel and read how I beg for a simple answer up to a dozen times, sometimes over years, instead just answering: "Go away, I don't want to chat with you anymore, because [reason]". Is that so difficult?
