They are not copyrighted NFT's. As you checked that my collection are verified on rarible NFT marketplace. I have applied for verification on opensea too. I hope they will soon verify my collection too.
Please read my idea again...
I meant that you are using Twitter brand and logo for marketing without their consent. It's like selling twitter t-shirts and stuff with twitter logo in them. You can't just say that you are not using copyrighted material when you are literally using their brand for selling nfts. There is even that bird logo right there on open sea.
And you can apply your verification all you want but i am betting that their partner
https://rarible.com/twitter/ wouldn't accept your marketing in a million years.
he doesn't understand it. his concern was on his NFT that has not copy right instead of thinking if his NFT was mentioning logo or big brand that already copy righted. This sounds illegal for anyone who know how copy right work.
I still don't understand what's a benefit of buying this NFT,
One reason, wasting your money instead of getting benefit from this kind of NFT.
What are your opinions about this NFT collection.

It's better for you to make your own one that didn't mention any logo or domain by the big company like twitter. Try your luck with your own original NFT
