This way of phrasing it is very bad. The idea of golden rule is to consider others as equal to yourself, and award them the same benefit of the doubt you would want others to give you before judging you.
It doesn’t really cover the cases if someone is actively malicious towards you. It’s basically outside of the scope of this rule.
In any way it’s too flawed as a base for further developing a moral system. I recommend to look into the idea of Original position or “veil of ignorance” for a different approach to the same problem.
