That has also been one of my worries, with a contest there will be inevitably some who will try to cheat. Which would then require some sort of controlling, but people getting disqualified if cheating was discovered and simple analysis on user entries might already prevent a lot of spam.

Besides the contest, do you think the general concept of organizing a mapping day/week/weekend is something people might be interested?
from looking at https://wiki.openstreetmap.org/wiki/Mapping_parties
and https://wiki.openstreetmap.org/wiki/Mapathon
that document some tiny subsection of such events - answer seems yes

It probably highly depends on people that you are trying to attract,
how you do this etc.

But I would recommend at least trying (as long as it is not blocked by COVID issues).

It may work nicely in combination with reporting black spots to local government
(I am assuming that in Switzerland it is an useful activity and that there are still
problematic spots fixable by local government but unknown to them).
