A suggestion would be for these types of tasks disable the tasking manager
from communicating with anything but JOSM its a bit drastic but where data
quality matters it is a very simple but crude method of keeping the very
inexperienced mappers away.

The other suggestion is disable Tasking Manager from permitting anything
but a JOSM mapper from validating but that would be on all projects.
