To give credit where credit is due…
The dragonball z model is now gone. Clicking on the link to it gives a “page not found”. I also did some searching and cannot find a lot of the stuff I was seeing originally - “Kingdom Hearts” for instance returned a bunch of keyblade models and such, and “Mario” gave a lot of mario models… It does look like efforts are being made to clean things up. Though I also worry that the DBZ model was removed specifically because the user said they didn’t make it lol
That said - all the links I tried in your post are still there… so it is hard to tell if maybe they are improving the search and its given more specific results without the copyrighted material in or if stuff is actually being taken down (aside from the Dragonball Z model lol)
But… it does look like something is happening at least.
Its very frustrating because I think the idea of a unified storefront has great potential… but it needs so much more care than has been given here
ADDITION: Sigh. I have no proof of this obviously - but I think that DBZ model was removed specifically because its been highlighted in a lot of places (either by epic or the “creator”)… Everything else by that creator is STILL THERE and a lot of them have the same “this is not my model but give me money cause i worked so hard to rip it from a game” bs lol
