FYI one of the primary purposes of this chan is and always has been sharing paid content, so you not consenting doesn't make a difference. Also, you could just be larping as her, who knows.
If you're concerned about loss of sales, I suspect this won't make a difference, as I'm not sure more than a few here have ever heard of you. You could almost consider this free advertising. I certainly do, because now I'm wondering if I should buy your clips. If you're concerned about your likeness being leaked, I suspect that this post won't make a difference either because reblogs of your posts on tumblr don't get removed when you delete your images or accounts.
