I checked the review queues as I usually do once per day. To my surprise, there were ~50 edits pending. All of them only changed minor elements, e.g. replacing quotes with the html equivalent. The comment contained an example.com e-mail address (which afaik do not actually work). I rejected all of them, but there are still some, so if you are reading this and are able to review edits, please do help.
Have you seen anything similar? Is this just spam, or could it be an attempt to exploit the SE system somehow?
