Unfortunately even copying and pasting info from your own twitter posts or other blog places leads to this thing... it's an account that goes around and looks of "plagiarized" content and it flags you. That makes your reputation go down considerably. Even if it is your own original content. And DEFINITELY copying and pasting other people's content (even with source cited) seems to be a big no no. This place seems to be all about the individual users own voice.

I have read tho that people don't get flagged when they post their own content (from some place else) with an explanation that they created that content and want to share it here.

It's all a learning experience for sure with a bit of a learning curve!

Good luck to your future posts!
