Haha, I actually don't know exactly what makes it happen.

It's an invisible thing unless you're looking at the source code. I always use the source editor, where that would never happen, but anyone should be able to see them when looking at diffs--either by clicking on "show changes" before submitting an edit (which is good practice!) or reviewing recent changes. That's where I spot them. :)

If these were coming from people who are planning to edit the wiki more in future, I would suggest using "show changes" before publishing an edit and then going into source mode to clean them up if they've randomly been added. Since these are random people who are probably only editing for the guild challenge, it's probably not worth trying to teach them that, though. I'm happy to keep an eye on it and clean them up occasionally if they keep happening, it's easy enough.
