Today I discovered (and confirmed) how to tactically edit questions or answers in order to generate exposure to the associated question(s). By editing a question (which might not be mine, which I have definitely edited at least one time prior) or answer (which might be mine and might have been edited by me prior), the associated question is sent to the top of the questions list.
The questions I edited had answers by me, which were validly "good" answers and had generated good reputation for me prior to my edits. The edit I recently made to an answer was intended to remove some unintended "all-caps shouting"; I had edited this answer several times the day prior. After I edited this time, I noticed an up-vote. Certainly it could have been from an edit reviewer, but I also noted the question appeared again at the top of today's question list.
To check if this wasn't a one-time occurrence, I then deliberately edited a question which I had also answered yesterday (and gained several upvotes), making actual, valid changes and clarifications. This was not the first time I had edited this question. The edited question jumped to the top of the questions list. As it is a good question/answer, within the hour I had suddenly gained upvotes for my answer.
Had I not re-edited my answer for the first question or re-edited the second question I had answered, I would never have gained those upvotes. I had artificially re-exposed the two questions.
This re-editing creates artificial exposure. While exposure to questions is fine, this is a way to game the system. I am of the opinion that there should be a mechanism to prevent this exposure. Any subsequent edit (second edit) a specific user makes to a given question/answer should not send the question back to the top of the list. I want to know if any sort of prevention mechanism is being considered?
