If someone attempts to slander you publicly after you block them, or if they do anything malicious towards you because of it, you can report them for it.

Part of keeping this platform safe for everyone, is ensuring that bad actors aren't allowed to thrive here.

The only thing I will say is that you should avoid sinking down to their level, and committing actions such as harassment, doxxing, etc. There is never an excuse for anyone to break the GameJolt guidelines, and commit actions that bring harm to others.
