I know editors of journals and they all get paid. However it is recognized that it is low and not expected to seriously complement their income. Think in the order of $2-5K p.a. All of whom I know have permanent university roles. It is considered prestigious for the editor/reviewer in the sense of service to their intellectual community, and to their resume; and their university to have their brand in positions of influence. Most tend to leave after only a few years and this is considered normal. The role of reviewer/editor is not significant enough to earn promotions - this must come from their research & teaching. They are required to declare any conflicts of interest for any papers under their review and they are simply passed to another editor. While the person who reviews your paper is usually unknown (through the review software/pool of reviewers) there's really little incentive to cheat on this as there exists sufficient high quality readers who can call out obvious bias/unusually low quality publications for the tier of journal. The most burdensome class of problem is the mass of papers submitted of insufficient quality for publication in the journal. These are quickly rejected but the volume is so high, and rejected authors often attempt to challenge. Sometimes they are rude. (I can't estimate the size of this from memory, sorry.) The upside is fortunately these don't require deep/secondary review.
