If you read the comments on your last post it looks like the flag came from - who asked you to prove your identity. If you do that, he offers a $100 upvote. Seems like a pretty sweet deal to me - prove you control the social media accounts you linked in your last post by linking to your steemit post from twitter/instagram .
If you're unable to do that, theres a pretty good chance you're just stealing someone elses images for profit - which is why you got flagged.
As mentioned, don't mass tag usernames or that will get you flagged too. Don't try and get everyone involved in this, it won't help.
