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!
