Final Fantasy Hacktics

Sorry I didn't know where to post this exactly. Long time lurker, messed with few mods and did a few minor patches for my own personal use. But a question I did have, is this site/spriters affiliated with dusk tactics by any chance? http://dusktactics.com/doc/gallery/screenshots . I noticed they are using quite a bit of sprites from your site, and I just wanted to make sure that you guys are affiliated and not someone trying to poach your sprites. Sorry if I am stepping out of line in anyway I didn't see anywhere to post this.
