What he did was indeed an inspiration and encouraged many people to do something and hope them the same luck, indeed no one forbids people from uploading NFT on opensea, but if you look at Opensea now it looks very bad because almost everyone uploads NFT on opensea outside of works of art, in my opinion, Opensea now looks like a messy market, because we can find things that are inappropriate for uploading such as photo ID cards, passports, bank accounts, vulgar photos, and even personal photos.
If they upload their photo ID cards or other private documents, it will put them in danger because that can attract scammers or bad people to buy and use it for their own purposes. They will not know their reason for doing that, and if something bad happens, the police can track them from the ID and get them right away. But the truth is they did not do anything wrong. So they need to be careful when they want to upload on NFT or the internet.
These days people are inspired by hearing stories of NFT being sold for a lot of money, and therefore they also list their NFTs with high prices thinking they will get sold too. No one tells that there are millions of NFT which are listed and never sold. We need people to be aware of this too so that they may lower their expectations.
Anything can happen in NFT space. It can be sold at high prices but it all depends upon luck.
They all want to make a big money from NFT and do that, but they do not understand that if they list their NFTs at a high price, they will not get attention from people unless they create something that is rare. But I do not think those people can do that since they only follow the trend without trying to learn more details on how to become a good seller. They can be inspired by others, but they need to find the most thing that people search for so they can try to create what the public want.
