She won't understand, because she refuses to. You can't 'win' with these sort of people, this person in particular is psychotic. You engage further, and you get dragged into the mud with them. It's best at this point to continue to flag her, get Steemcleaners to continue to flag her plagiarizing as well, and ignore her. Get other people that you know to flag her, I flagged her recent post as well. If you engage her, you give her exactly what she's asking for - notoriety and attention. Don't talk about her by name, don't respond to her spam. She's currently thriving off this drama, most people like her do. Once you realize it's fruitless to continue, once you realize how a person is, withdraw from the conversation.
