There's always going to be someone out there who dislikes, or hates you. You can't do anything about it, because you can't please everyone, and that's okay. I believe you shouldn't pay any mind to anything that comes out of that confession account, since it was clearly made with the intuition to stir up drama. And you should especially not listen to anyone who refuses to be straightforward to you about their opinion on you, and instead chooses to hide behind an anonymous facade. Simply look away, and move on, because these people aren't worth your time.
