No at all, first it fits with the scope of the journal, second, read the abstract to see the originality and novelty of the work, third, go through the references to find who are the best reviewers to contact.
I have yet to serve in the capacity of editor, but if I heard that an editor was doing a background check on authors before submitting a manuscript for review, I would never submit anything to that journal. In my opinion, that kind of behavior would violate the spirit of blind peer review.
In my opinion, as Professor Sherif said, the editor will check the novelty of the work with its originality and whether the manuscript is matching with the theme of the journal. Maybe at the time of reviewing, the reviewer can compare the previous works of the author and can probe a question what is the difference between the proposed one and the published one.
There are the reviewers who propose to accept or not. A good reviewer should also tell exectly what is missing or the needed improvement, or subject problems.
