As some of you know, I'm a scientist. I recently did peer review for multiple papers for one lab group. Both papers were rejected. One was rejected over my objections, one was rejected on the basis of my recommendation. I had reviewed the paper I rejected anonymously. Not because I was rejecting it, but because I was rejecting it procedurally, and there would be no reason for the author to contact me with questions.
A member of the lab group contacted me to gripe at me, and doxxed me for my rejection review. I don't think this person meant poorly. In the case of the paper rejected over my objections, perhaps I could have structured it differently to make a stronger case for the paper (I generally don't feel this advocacy is necessarily the prerogative of the reviewer, though). This person is someone I've been friendly with in the past, but being doxxed for a review really doesn't sit right with me. But this person also isn't an author on the rejected paper, so going to the journal and tattling on this inappropriate contact feels like it might punish the wrong person or people.
I think I'm just going to let it slide, but if it gets weirder, I might take action. There's a lot of debate in science about open vs. closed reviews, blind vs. non-blind, reviewers being anonymous, etc. Regardless of how anyone does feel about those questions, in both of my reviews, I acted in accordance with journal policies. Jumping in to decide I don't require my anonymity wasn't this person's call, and it grinds my gears.
