Um, yeah, they seem pissed.
They've been aware of the infringement for a while, apparently, and have made efforts to get in touch with us, but didn't really know how to do that without joining Wikidot (which they had no interest in doing). We might want to get an attribution in soon, maybe by editing the first comment in the discussion thread to include whatever copyright information they want posted.
Question: Somebody cropped the original watermark out of the photo before using the picture. Should that be something that we specifically forbid, if it isn't already? It's a direct attempt to circumvent giving credit to original artists. I'm not saying Adam Henderson (the author of SCP-111) needs to be punished in this case, since we can't prove he was the one who removed the watermark anyway, but shouldn't it be very much against Site Rules to use someone else's work and deliberately take steps that avoid giving them credit? Or am I just over sensitive about this?
