I was also curious about that. So i used: https://web.archive.org/web/20201115000000*/https://mvmnt.in/about/ to see if he was listed in that about section previously and the oldest history they have for mvmnt.in/about was from august 10, 2020 and luis wasnt listed there then either.
where do you remember him being listed on the website so i can dig a little further.
