I created and published a 'Grand Illusionist' homebrew monster some time ago. Recently I noticed a new entry in my homebrew creations I am certain I've not made, it looks like a copy of my 'Grand Illusionist' but renamed to 'Lydia' and this version is not published. Looking at the last modified date of this 'Lydia' version I am absolutely certain that I was not the one who edited it.
Seems to me I've been handed someone else's renamed copy of my original published entry.

What you describe should be impossible for a number of reasons. Mainly: You can't copy a public homebrew and make your own version yet.
The only people who could so this are you, a mod (possibly), or someone else with access to your account.
