This is really good advice. It can really mess with your head if you let it. The worst thing you can do is give trolls any sort of credence. Once you decide to stop posting, they think that they've won, but they haven't.
I've had critics and haters on this platform before, but these people (with a few exceptions) are either no longer on the platform or if they are, they aren't producing content.
Keep on posting regardless.
