In other words, it was an extremely, extremely low-probability, accidental discovery.
The chances of collision is so low that it is impossible only
if you created the seed phrase yourself using a strong random number generator. But this is not the case here. You say you have found these words on the internet (on Facebook) and you claim it is a scam attempt.
The chances of it is actually very high to see the words used in the same order they were posted to generate a wallet with transaction history (the "scammer" did that intentionally).
Since my previous posts mentioned specific mnemonic word orders, I cannot disclose the detailed mnemonic phrases. If I did, others could use the number sequences I previously mentioned to open that third-party Bitcoin wallet, which would expose their private key and compromise their privacy. Please forgive me if my Google Translate English isn't perfectly accurate!"
"Regarding what you mentioned: if those 12 mnemonic words are combined in the normal sequence (1, 2, 3, 4... 12), the resulting wallet is that of the Facebook scammer."
"However, using the exact same 12 mnemonic words, but in an interleaved sequence like 1, 7, 2, 8, 3, 9, etc., results in that third-party Bitcoin wallet. The key point is that this third-party Bitcoin private key wallet is completely unrelated to the scammer's wallet – they share the same mnemonic words, but the order is different!"
"Most importantly: that third-party wallet, generated by the 'chaotic combination,' was not newly created by Electrum during the import process. It has existed for several years and has recent Bitcoin transaction history from the last ten-odd days. This is truly bizarre/magical."
"I'm not sure if Google Translate perfectly conveys my meaning in English, haha."
