You're right, I think that's part of the reason Steem is volatile currently. I have seen many bloggers with well established blog come to Steemit and leave because of the plagiarism accusations. Criminals are not forthcoming, they hide and lie, even though being honest is the best way to fight anything you are the one treated like a criminal. Stay Strong. Just keep doing what you're doing. It is honestly the best defense. As long as they don't quiet you, you win.
