Hi, sorry for the comment in Italian. Seems good, thanks!
As for the Molfetta fountain I meant the one here in this changeset: https://www.openstreetmap.org/changeset/163863816
If you've noticed that it's not working you should just tag it as disused, I also suggest to add/update the check_date field in these cases.
The one in front of the cathedral doesn't exist anymore indeed, I can confirm
