Well, this sucks. The fact that steemit is decentralized is not at all a bad thing. What makes it bad are users like that. I personally have watched almost all of your videos on steemit and I do agree that you put a lot of time and effort in these videos because my small introduction most took me more than an hour to make and I could assume what time you take to put out these great content. Honestly, you're one of the best content producer here in steemit. And I also feel bad that you lost your $230 because of him. Will resteem the post because it deserves more attention. Lets hope that there are no more users like him.
