It's not really that surprising when you think about it, but there have been a couple pages where I find that the author listed was modified or incorrect, seemingly intentionally. This page will track the pages where I know this issue occurred.
This post is also a reminder to myself for the future to check pages more closely to see if there are any more of these...
- NIGHT RACE - original submitter claiming credit was not the author
- Attack on Titan Tribute Game - modified a few years after submission by a seemingly random user
Do more exist? I have no idea, I found both of these by accident. I suspect there may be more, hence this post. If you uploaded programs here at some point, check your own pages to see if they are correct.
