Hello guys!
I'm dealing with an art-thief lately on Instagram, no surprise here. But the thing is, the little girl is claiming to be me, and she don't want to give up. Instagram took down all my reposted comics with my DMCA reports and now I get this:

I won't edit out usernames, she changes them constantly anyway, I'm so annoyed, and I've reported them with abuse... :/ Really, even if you are a little girl, YOU DON'T DO THIS!
And what does she expect? I make a tutorial on how I draw some lines and then what? It's not how you learn to draw....
Have you ever dealt with something like that before? Beside reporting it, and hoping Instagram/Facebook will do the right thing, what should one do? I've tried to report her several times for impersonating me, but Insta only cares about real life identities, not online ones.
