I have been invited to review a paper for a good journal. The paper is certainly on my expertise areas. However, I have reviewed papers for the same authors in the past (and accepted some/most of them), and they tend to be quite hostile and rude in their replies. I try to be polite with my comments, even with the major ones, but these authors seem to take simple things as pointing out typos as a big offence and reply with a very harsh tone. Editors seem to not care at all about this, perhaps because one of the authors is an authority in this area. I was thinking of declining the invitation but I was unsure if I should indicate this reason in my reply. This is, in this case, I am a good fit for reviewing the paper but my reason for declining is that I do not want to go through this sort of unpleasant moments again.
