I don't see a problem here. First of all, the "skip" option only removes the post from your review queue, not from everyone else's. If you skip a post, that won't make it magically disappear from my queue, only from yours.
In any case, the more common problem is precisely the opposite of what you describe. Since finishing a certain number of review tasks grants you badges (namely, Custodian, Reviewer and Steward), some people will make bad revisions or revise things in no need of revision just to get the badges. That's one of the reasons we have review audits.
In other words, quite frankly, I wish more people would "abuse" the system as you describe. That simply results in more edits and increases the overall quality of the site. If the editor in question chooses to then skip the review item in their queue, that's their choice and doesn't affect the rest of us in any way.
Finally, note that having a suggested edit approved i) only gives a measly 2 rep points and ii) only gives rep until you reach 2k reputation and can edit posts without requiring approval. After that, there is no bonus rep awarded for edits. So, your claim that this is a "lucrative" way of finding new posts to edit doesn't make much sense.
