Ok I looked at the history for the pages I edited on May 16, and I did NOT do those intentionally. I was only just trying to add categories and not adding source codes. I think there was a glitch on my end and I'm sorry it made it seem like I was adding the source codes when i actually wasn't. It was a editing glitch, and I know better than to spam a page.
It's good to know that you weren't actually spamming the pages, but the fact that it kept changing, well, if it changes everytime, I can't monitor every single page, so unless you can fix whatever it is on your end, I can't have you changing the templates to source code. Of course, when you can fix it, we're happy to have you!
