Nftsea, located at nftsea.net, claims to be a new platform with a fork of Opensea. They describe to be a hard fork of OpenSea but have no connections to them. I just joined their group but I noticed that many members are made by bots and there were almost no admins/mods which was a surprise for me at +40k members.

A further look on their website whitepaper at Page 9( https://nftsea.net/whitepaper.pdf ) claim that John Crain is the founder of NFTSea labs which is not true and truly made by this scammer.
Asking John Crain directly on Telegram and it was confirmed that NFTSea project is a scam. By looking at their contract address many people just seem to lose their money.
