Eh, honestly that's OK with me cause they took a bunch of ideas and made something unique that promotes creative thinking! IIRC they asked for permission beforehand (this was months ago) and the fact that they told people not to remove credits is good enough for me. They didn't edit my image and included a link to my page so yeah

But in general, I tell people not to edit or repost my stuff because 99% of the time they don't credit me, they don't link back to the source, or they claim it as theirs when it's clearly not.
