I definitely agree with giving credit where it's due. I once designed a website and filled it with my artwork, which at the time was a very personal outlet for a lot of stuff that I was feeling. I later discovered that someone had not only downloaded my site design, but all my artwork along with it, and put their own words over it and credited themself for the design. It wasn't for profit or anything, but just seeing something that was so personally mine out there with someone else's name on it really upset me.
On the other hand, in this situation, I can see how it was just a mistake. If the photograph in the caption contest thread did not clearly say who the photo belonged to (and I don't know because I haven't seen the thread), then I know from experience that it can be SO hard to track down the owner of a particular bunner, or photo, if you're not familiar with that bun.
bunnycute, I really hope you don't leave RO for good. I know there are a lot of members here who would love to have their photos end up on LOLbunnies (myself included), and I'm sure that the only reason ADEE reacted the way she did was because of past experiences.
