I've received an invitation from an editor of a journal to review an article. After a brief reading, I've determined that the article's scope is beyond my area of expertise, leading me to decline the invitation. In the invitation letter, the editor kindly asked for alternative reviewer suggestions in case of my declination. While I am aware of potential reviewers who would be suitable for this article based on my past experiences, I have no personal contact with them (I knew them solely from reading their works).
Should I include them as recommendations?
