I see nothing wrong with people wanting to add watermarks on their pictures. After all you are just protecting your work and you don't want anyone else using your photos in any inappropriate ways. I wish the cosplay.com has an option where it protects your photo from people who just copy and paste pictures and then put your photo through photoshop hell and removes the watermarks and such.
I disagree about putting the watermark in the corner of the photo they can just trim your photo in MS paint/photoshop if they want. It's not that hard. I get what you are saying about you want to look at the cosplayer not a water mark. Have it hidden somewhere, where you can still see cosplayer and cosplay but not somewhere you can trim out.
