I feel like this is the first one I’m aware of that is directly user-editable, which increases the chance of staying up to date, especially if each point is marked with when it was last updated.
EDIT: Oh, it’s not possible to remove or edit markers, only to add them, unless you save the magic URL from when the marker was created, or possibly are some sort of admin or maybe pay money. :-(
For my own reference, the magic URL to delete or edit my marker is: https://www.zeemaps.com/edit/WCXZQ_0pN-M2vwfx4VBR-g (I see no harm in making this public, since anybody can create an unauthenticated marker with my name on it in any case.)

Just contact me if you lose your URL. I’ll delete the marker and you can make a new one.
