A token called $YEAR invited people to connect their crypto wallets and see a "year in review"-style summary of their 2021 crypto and NFT transactions, with an airdropped token reward based on their activity level. Some community members audited the contract to look for signs of a scam, but missed a few lines of code that enabled the creator to prevent people from selling the token. With people only able to buy the token (on secondary exchanges) but not sell, the price rose, encouraging others to buy in. Only 30 minutes after locking people out of selling, the creator drained the liquidity pool of 59.7 ETH (about $225,000), dropping the coin's value to 0.
