Yes you can share the same content in two separate posts with two different languages. I think you can do it without the fear of flagging. In fact it is more encouraged in some cases to share your content in multiple languages as it has the possibility of increasing genuine engagement on the platform.
I have seen several prominent users on Steemit do the very same thing. Using languages like Spanish and English or German and English for to two separate posts with essentially the same content matter.
Good read. But i'm also the guy that puts everything into BTC hoping to get rich.
Thanks for answer :)
