    R2S was a painful one, but Lachlan was a dream of a security researcher to partner with. Not just from a responsible disclosure POV, but things like hopping on multiple calls with Meta and our team to help us validate remediations. Thank you Lachlan for helping make the internet safer (and great job on figuring out this 'labyrinth' of a vulnerability)

    >> Amazingly, despite being a weekend, the Meta team triaged, reproduced, and confirmed my submission in around 17 hours.

    Incredible. Realize what you have done from start to finish (with confirmation) in < 24 hours.

    Nice read!

    I love the "we are so back" vs. "it's so over" graph. Defines so much of this type of work. "Wow? ... nah... WOW?! ... nah..."

    Haha, nice.

    One correction: The link in "To be honest, I'm not even sure if I understand it, but it's on my GitHub." goes to the wrong file (01 instead of 00).
