Behold, the Media Matters report that was attributed as the source in the CNN article.
I understand wanting to know what evidence someone has for an argument, but when the source is attributed in the posted article then demands for proof come across as sealioning which is very much discouraged on Beehaw.
For those that don’t feel like reading that Media Matters report, the account in question was openly and explicitly neo-nazi, and Media Matters has screenshots of a number of posts with memes praising Hitler, Holocaust denial, and “great replacement” memes. There’s also a meme that just says “It’s okay to be a national socialist” which seems about as pro-Nazi as something could possibly get.
TBH, unless you got extraordinarily lucky (or had the right connections to get somebody to push your NFTs) you probably would have wound up losing money. “Gas” fees on the Etherium blockchain can get really high, and I found this article that has some really good numbers on median prices for NFT sales. For the time period their data came from (a random week during the NFT gold rush) about %30 of artists sold for prices low enough that they were likely to barely break even or possibly lose money on fees. Virtually no artists made any appreciable money on NFTs even during the biggest hype periods.
