Well, that's a shame. Then again, Gaia is not renowned for its writing gallery; -most of what I've seen there are just poorly-written angst drabble. There isn't enough character space to allow us to write proper critiques either, so the programmers probably didn't expect much.
Then again, there shouldn't be a legitimate reason for them to report you. “He was being mean” –because THAT would go over well with the staff. Constructive criticism is not the same as harassment, and if they ever expect to pursue writing, they need to get used to being corrected and/or receiving negative opinions. (Oh dear, I sound like I'm ranting, don't I? Sorry. XD -And to think I used to be one of those people who hated when someone corrected my work!)
I think it's cool that you have been published though. I, also am just a "writer at heart" and have not yet been published. (I haven't tried to get published yet either. I'm too self-criticizing to feel very comfortable with anything I've written.)
Do you like creative writing or are you more into journalism?
