What's your experience with online scammers?

As a woman I've come to realize that this is something I don't have to deal with at all. In some spaces where there are profiles and fake engagement, it seems really obvious to me, but in others maybe it's more subtle, plus they're not targeting me. Is it more prevalent in spaces that are more male dominated? How do you build discernment and guard against it, does it change how you interact with strangers online? Do you think it impacts how you think about women in general?
