You might want to send the staff an email or contact them through their tumblr. Unfortunately they're not active in these forums.
Also, from what the staff has said, most (or all?) of the questions were user-submitted back when there was that option, so people were probably copying your questions as they weren't able to come up with ones of their own. (Or it's just a super freaky coincidence but I doubt it if they're word for word)
dA is a huge community. You never know, and I agree with Lime. But there are a lot of common questions to ask for character development, and the ones they are asking seem simple enough that it wouldn't be that they copied straight from your sheet (except the sanity/order/crazy world one). Presently, I feel like the best you can do is assume best intentions. The staff probably didn't know. :)
