Is there a reason he didn't just use a passphrase?

Ah! He's fine and I have asked for his permission to post about this and find a more better solution.
Also, I'm not the only one who knows about this, but the entire friend circle and his family. Few of them have also posted this on Reddit for fun too! 

(HE KNOWS AND CAN SEE THIS SN POST ANY TIME BECAUSE WE BOTH ARE ON SN AND THIS POST WAS MADE AFTER TAKING HIS PERMISSION) 

Thanks for your concern though!

My friend keeps his seed phrase in the most bizarre and reckless way imaginable

Your friend would probably have been fine but for you doxxing his setup here and incentivising SN autists to scour Twitter for bip39 words. Accounts were probably made at a similar time and have a similar post count. Posts were probably made within a certain time zone. Don't even have a Twitter account so don't know how the search works. Probably manipulated by algos and no API access do despite your best efforts here your friend should still be OK, unless someone is an insider at X or has some kind of API access for some reason.
