fraudulant posts, how do I handle someone stealing my artwork?

First of all, I'm very thankful for @yourservice for bringing this to my attention, and @dubceereviews for defending me when it was brought into question of who the original artist was on a recent post, well, unfortunately a couple recent posts. I put up a post of a painting I did (shown below), Including a breakdown of my process and another steemit user @mughalmirza stole (not resteemed) the post word for word, and is continuing to collect credit for my work as well as the money accumulating from it. Now ideally I'd like to burn this person, take the money and smash there computer, but I don't think I'm able to do that. So, how do I handle this? the only thing I've seen for fraud on here is through the steemit chat, but my computer isn't really allowing that at the time. There has to be another way right? because I could use a little help and insight on the subject.

you can check my instagram account ( www.instagram.com/honeycombwinnie ) to verify my credibility of the artwork being indeed mine and I have also included another picture of it, where it lays with other works of mine (including additional pieces I've put on steemit). Thank you all in advance, I truly love the steemit community and I believe in it, I just can't believe someone did this, I suppose it's a compliment, but to hell with all that. It ain't right.
