The oldest GEDCOM on my list was uploaded on 21 May 2018 and last edited on 22 May 2018, so I think it's safe to say the 60 day removal isn't working. However it is on the list of things to fix (see https://trello.com/c/R6Qdn4mz/111-gedcoms-may-not-be-deleted-when-they-should-be) and is in the "Up Next" group, so a fix may be coming soon.
