An Epiphany, I Just Had One!

So, how many of you are members of FictionPress.com?
Not many? Some? Most?
Okay, so one of the features is you absolutely cannot highlight and copy. It physically will not let you. Making it extremely hard to plagiarize from the site, unless you know how to access the source code and copy the writing from there.
I'm under the assumption the 17 year old doesn't have a background in HTML like me (even though mine is basic, we learned about source pages) and wouldn't think to do that.
Which leads me to believe that my thief is one of us.

SHE'S BEHIND YOU!

No. But in all seriousness. Its the only other place I have my stories posted and it would be the only place she could get it from.
Not hating on you Mibs but I'm paranoid as fuck now. What if its someone I talk to? What if she's reading this right now?
GO AWAY YOU GODLESS SWINE! I KNOW YOU'RE WATCHING!
The fear is real guys.
