I submitted a paper together with other people to an important journal. A couple of days ago we received the answer from the editor and the paper was rejected (I was 3rd author) with very bad comments. One of the reviewers wrote that the paper was lacking innovation or originality. Another one sent us more than 20 comments. To be honest the comments weren't really appropriate because we did particles loaded with gold or FITC and one of the comments was "It seems that the FITC and gold are encapsulated inside the nanoparticles, not the other way around." He did not understand a lot but still, he also did a lot of interesting comments.
Anyway, the main author yesterday emailed the editor saying that the reviewers do not have enough knowledge to correct this paper, that they are unqualified and that people like this should not correct this kind of work. This person sent the email to the editor without speaking to any other authors, therefore we discovered today what happened and some of us still don't know.
Do you think that the journal, following this email, can do something to the authors of the paper? Like, e.g., sue us? or ban us to publish there? or stuff like this?
What should we do now?
