Systematically refusing to do reviews really doesn't help your changes of getting your own papers (and those of your grad students) accepted in the future. Editors have a lot of freedom in deciding what's on topic for their journal.

In my field (theoretical CS), I have never heard about a journal refusing papers from authors that have declined to review for the journal. In fact I would consider this extremely shady: journals shouldn't handle papers differently depending on the identity of the authors, no matter the reason.

Well they wouldn't make it obvious. It would be rejected for other reasons.
