This user has appeared a few times to make edits that are redundant. I usually just remove the edit or revert. On the rare occasion, I'll find a way to integrate their edit (The like to add stuff to trivia sections, some trivia points are already mentioned in the page/article, so they become redundant).
I switched it up a bit and added why I removed the points in the edit summary. But I came back a few hours later to find they had but the same information back on the page that I had removed/edited. It's getting frustrating.
This user appears as an IP address, and has no talk page. I am very much all for talking it out, but I can't as they don't have a talk page. How do I handle this? I don't want to ban them as they aren't trolling, but it's annoying nonetheless.
