Do you think there is confusion regarding the forum ranks? I have thought about how all the forum mods, and those access to the database pages, as well as the actual admins and those who have access to things behind the scenes (the real hands on stuff) all just say "Administrator" on the forum. If it is a big deal, perhaps we can make a new thread in this section and see what the feedback is like.
Most websites that create a database, as in a historical list of products released about a certain subject will fall into the same category that the Mediawiki based sites do, for example. They typically operate under fair use. The majority of the images that I put are ones covered under fair use by other websites. The ones made from Ebay are weird because by their terms, they own non-exclusive rights to the images and it can be up to debate. For ebay listings, images are claimed by Ebay and Ebay only takes action against fraudulent use on their own system. If the image source also has no rules about usage, what does it mean? I'm no copyright lawyer...
BUT I think we would have no problem to remove an image on our site if a company or another person (who has not been a member of the site) requests it to be removed and/or replaced. But I think that someone would have a difficult time proving this since our images are so small, and also would have to prove why the usage doesn't fall under fair use. It's a "we'll see what happens when it happens" thing I guess. One company that could complain (that I've brought up somewhere before) is Limited Run Games, since a lot of those entries are just using their watermarked photos.
The Facebook Pixel is not anything new. Websites have been using 1x1 tracking images since the 90s. This has nothing to do with image files at all. If you are referring to embedding an image with some other sort of data, I'm not sure I can think of any valid way that information would be retained. When an image is uploaded here, the image that shows up on the page is edited and re-saved to JPG, and the original file is discarded. PNG gets changed to JPG, so even a vector PNG would be flattened and any hidden things would be erased. And EXIF data does not process either... I'd rather not see what happens if you try to upload an image archive (I won't say more) but I think either you'd end up with a broken image or an all black image, and the archive would be missing.
