Why my posts are flagged?

I am a new comer to this community and to NeuroScience.
I asked a few questions, maybe too basic, but after a while I received a notification that my posts have been flagged by community member(s).
Exact message:

Post hidden by community flags

Can someone please suggest, why? I am here to learn and share.

This was just a glitch in the system. Sorry for that! Your posts have been unflagged.

Thanks ChrisGorgolewski. Hopefully we have a system where we can send a notification to members once we find some issue with the system, so that everyone knows what happened and not be worried.
