lmao, it's not even that, it's not loan, it's "loan protocol" which means it's not real loan from bank with real money, but "loan" of dork points from shady "protocol" and that can mean whatever. that means that nftbros didn't pay for this, they only paid for loan interest, that is until they didn't. it looks like the bigger sucker was whoever gave them loan in the first place, but so is all of crypto, layers over layers of clowns and frauds
Taking out loans via defi scripts and getting automatically liquidated is definitely a thing yes. Sometimes, they even get liquidated by bugs in said scripts. Remember though, it's all crypto funny money involved usually with people who got in before it got manipulated to hell.
