A great initiative. I noticed someone pretending to be someone else (a popular youtube channel) copied all of their vids into steemit and made their username the same. I upvoted and commented on some of the vids but something didn't seem right. I went back a few days later and the vids had been deleted. I went through every comment and upvote and removed them as it was clear they were stealing content from someone who had worked very hard to create it.
