I just reply to everyone with my expected salary, which is 30% increase of my current salary. If they are not close to that number, then it is better to not waste our time.

I've been in the employer position (as a hiring manager) and in the Employee position. I know how much I am worth (or what I want to be worth), so I don't really care about playing games and haggling. I'ts ok, my value might become lower in a recession, or when trying to get into new verticals. When that happens, I'll adjust my expectations.
