i answered to that in one of your recent posts because another Steemian wondered about your low reputation score.
Maybe it's just a system failure. Keep asking, maybe it's because someone of the whales was affronted by your topics. I don't know. Ask the following:
Did you get a warning for something in of your posts before?
Someone left a negative comment in your posts?
If you're not sure try to ask directly Steemians who flagged you und til you get response and maybe you can change something. Good luck!
thank you
