Collections

A while ago, when AO3 started allowing people to make their own collections, I remember something about people collecting works and then deleting the collections would make your own fic disappear, and it was suggested we set our requirements to "must ask" before adding to a collection. Which I did--I don't recall why that was an issue, or if it was ever resolved, because it wasn't something that I figured would ever affect me, but I got a request to add a fic to someone's Stucky collection recently but wasn't sure if that was a good idea or not. The FAQ info about collections is woefully outdated and doesn't include personal ones, or information about this issue.

If you allow someone else to add your fic to their collection, and then they later delete that collection, will it still delete your fic too? Or has that been fixed?
