I don't think so, some people have solved Cicada 3301 puzzles way more complex without anybody's help.
Yes, but we've had the explicit information to
NOT brute force it. I agree that the last stage wouldn't have been obtained without OP's hints but it's over now. Nothing you can do but do something else. It's the internet, after all.
Thank you to all the guys and girls that helped solve each step of the way. It's been a great game of cat and mouse even if the source material could do with some polish.
I look forward to playing again. Under a different handle, of course.
Love, sidekick.
