His reply looks and sounds like a typical reply from ChatGPT or similar AI chatbots.
It's just he's too lazy to read the entire OP or missed that part to include that there are 30 to 50 words in the list.
Both of you should see his feedback. He already received 5 feedback since late of last month.
Without sensible clues how his "puzzle" was constructed, which the OP apparently doesn't have anymore, it's not likely to significantly reduce the amount of possible word combinations. The sample space is very very likely simply too large.
In addition, OP never confirm whether his 30-50 words list exist on BIP 39 (total 2048 words) or old Electrum mnemonic (total 1626 words) which could add more search space.
