Social token platform Roll hacked for $5.7 million
Private keys for hot wallets on the Roll network were compromised, allowing the theft of around $5.7 million from various "social tokens". "Friends With Benefits", an a16z-backed DAO with an associated token that allows those who are approved by the DAO and can afford the ~$8,000 entrance fee access to exclusive parties, was one of the tokens affected, and it tanked in value by about 96%. Roll apologized and announced a fund to help those affected, though the $500,000 fund was only a small fraction of the money lost.
A headline-making $69 million NFT sale looks an awful lot like a publicity stunt
Vignesh Sundaresan's $69 million purchase of an NFT by artist Beeple made headlines. However, Amy Castor outlined a few days later that Sundaresan is a business partner of Beeple's, and that Beeple himself owns 2% of the B20 tokens created by Sundaresan's cryptocurrency investment firm. She speculates that money may not have exchanged hands at all, but that Sundaresan and Beeple orchestrated the purchase to artificially inflate the value of the work, increase Beeple's popularity, and draw attention to Sundaresan and his company.

Indie Developer sells commissioned pixel art as NFTs without permission from original artists
Jason Rohrer, developer of the 2014 indie game The Castle Doctrine announced his plan to auction 155 of the digital paintings that he had commissioned for the game as NFTs on the OpenSea platform, without ever requesting permission from the original artists or informing them of his plan at all. In an email, Rohrer told Kotaku that he hadn't asked for permission from the artists to sell the works as NFTs "mostly because having email conversations with 50+ people would exceed my bandwidth as a solo creator." At least three artists asked for their work to be removed from the collection.
An NFT artist changes all images in their collection to photos of rugs to make a point about the value of NFTs
NFT artist "neitherconfirm" created a collection of 26 NFTs of stained glass-style computer-generated art. After release, they changed the art for each NFT to a picture of a rug, an apparent reference to "rug pulls". The artist wrote on Twitter, "Nobody got hurt. It is pretty easy to change the jpg, even if it does not belong to me or it is on auction. I am the artist, my decision, right? A thread from somebody making his living with art irl about the value of NFTs... All discussions about the value of NFTs are meaningless as long as the token is not inseparable from the artwork itself... What is the meaning of creating an unforgeable token on a highly secured network if somebody can alter, relink or destroy your possession? As long as the value of your artwork is reliable on a central service you do not own anything."

Meerkat DeFi team briefly rug-pulls $31 million before returning the funds with an odd explanation
The team behind the Meerkat DeFi protocol claimed they had been victims of a hack, but subsequently disappeared from the web after the equivalent of $31 million in Binance Coin (BNB) and BUSD was pulled from the project. Two days later, a developer for the project wrote that the project had been a "test [of] user greed and subjectivity", and aimed to "[help] users realize the potential danger in smart contracts [and] the subjectivity in the audit processes of audit companies." The developer wrote that all victims would be refunded. Some believed that the bizarre "experiment" explanation was to cover that Binance had stepped in to address the scam.
