It does go against the premise of cordiality that Steemit demonstrates.

This premise, however, is an effect of rewards being potential to posts and comments. Thus, the prospect of 'doing something' is also counter to the same source of cordiality, as it would entail potential to draw flags.

While some folks will do this, in some circumstances, such as your own, where you have a dedicated following with sufficient stake to counter the flags and remain immune to them, those circumstances are both rare, and unlikely to pursue the offender beyond the limits of your blog.
