On the contrary. Several publishers got removed for selling stolen assets after the messy coder published a video and this thread was created. Or would you prefer no information at all?
At least you can find something about a publisher. eg Rivermill Studios was on the store for years, even in bundles. But this one was removed too fast, I suspect the publisher removed himself, but I don’t know. Or Arkaya Venture Limited has quite the collection of pricey assets, yet they are stolen. Golden Rock GTeam is selling characters which look like the Koroks from Nintendo. These will definitely get you into trouble if you use them. Would you prefer having information that you can find or having no information at all. Fact is: People won’t get their hard earned money back while the reaction time of Unity is very questionable.
