I figured out something about Instagram - why the only comments I see on smaller artists/models' accounts are creepily positive, to the point of being bizarre. They block any comments which aren't. I saw one last week which was something like 'Excuse me for saying so, but x part of this looks unfinished/looks like it needs more work' which is a fair enough comment. Checked back a couple of days later and the comment was gone.
There could be 50/50 positive and negative comments.
