Update, the ghost profile is gone-gone. So you can at least delete your accounts. But I would definitely stay away from that site. Or not uploading your art at least, until we can say for sure the site is going to be legit (which I have my doubts about)

I'll check back in later with updates whether it got deleted properly or a 'ghost account' remains after deletion. Because that would suggest you can't delete your stuff properly. I have a feeling they use the site to farm for new NFT to do another NFT scam in the future.

I joined the site myself a few days back, thinking I found a tiny treasure in the making. I deleted my account today but it seems to struggle to delete the thing properly? I don't come up on search anymore, but my profile still seems there when I go on the site. That feels shady too.

Just putting that out here as a warning in case you saw the site, or advertisement for it, and you think about joining. The whole thing reeks of SUS to me. Just look up Mostafa Nassar and NFT. Or check out OctoQueenz pinned post on twitter. It's just very very shady.

For me, that doesn't sound like a 'safe haven for human artists', when one or both of the founders used to do NFT scams and praises AI as 'the future for everything'.
To each their own, but I'd stay clear from that site.
