You make a good point, and we have discussed this before as well.
There is a thin line between providing incentives and ways to get
tedious work done more quickly and efficiently, and real
'gamification' where there is a real risk of quantity over quality.
This is why MapRoulette does not do any of these things - there is no
ranking, there is no badges or prizes, exactly because I don't want
folks to go fix lots of things quickly just for the sake of it.
That said, we did have success with the Baseball challenge - at least
I did not hear anyone complain about bad baseball fields added after
that was done. So I think there is room for a little more game
incentives in this kind of tool, but I definitely don't want to rush
to achieve that, especially because it seems to work just fine as is.

By exposing these bugs this way, you put the responsibility in the
hands of the armchair mapper, and that is a leap of faith I am willing
to make considering the situation here in the US. We don't have the
luxury of 5 mappers per square km here and we will never have that -
not only because we don't have the population density, but also
because of the vast stretches of land that do have road coverage but
almost no people, and it is very unlikely for someone to take
ownership / stewardship of those stretches. But we still want the bugs
fixed, so I am happy to resort to the second best solution, which is
to carefully direct armchair mappers to the bugs and leverage the
crowd to fix them.
For the same reason (and other ones that are irrelevant here), I
restricted the scope of MapRoulette to the US initially. I think that
a tool like this makes much less sense for a mapper-dense and
population-dense country. I am looking at integrating with KeepRight,
but we will need to have this discussion before that can happen.

There is already a SKIP button in MapRoulette for that very reason.
What I will also do is add another word of warning to MapRoulette to
please skip stuff if you're not sure how to fix it or you can't
appreciate the situation on the ground from aerials. And yes, I do
think the US is predictable enough in its road layout that I would
trust someone from say Florida to clean up the beautiful state of
