Heavens! Sorry you went through that, Preeti! I've had private notes of this sort on my self-published posts as well. Completely uncalled for. If a writer does not like a submission guideline they are free to self-publish or take it to another publication that does not have that requirement. As editors we do our best to finetune drafts and publish them --donating our time and effort. No editor deserves this treatment. Hugs! 💙 As one of the kindest persons I know, you certainly did not deserve it.
