Am I paranoid or have the same thing happened to you?

So everytime I become single again, all the ex dates or ex boyfriends suddenly start to write to me and call me. FYI I've blocked all of them but they still find me in other ways when I am single. Is there like a signal that tells them I am single? Or do they stalk me on social media to find out if I am single?

It's very weird.
