I discovered recently that any questions I edit get put back up at the top of the questions queue. This means that if I answered a question and didn't feel like I got enough upvotes, I could just go an edit the question to bump it back up to the top of the question queue to increase its visibility and improve my odds of getting more upvotes.
Given this, is it ethical/fair for me to go back to my older answers and make (reasonable) edits to the question in order to bump it back up into the queue? I've never deliberately made a trivial change to a question in order to bump it - I always make a good honest effort to make the question more readable or more grammatically correct - but I'm starting to think that I'm just unfairly gaming the system by artificially earning more upvotes than I normally should be getting.
Any thoughts? Should I stop making edits like these?
