No! it's an option to ignore the task if the user doesn't think
there's anything wrong. Maproulette is based on guesswork. A task
doesn't mean there's an error that definitely needs fixing
I presume the "false positive" button is for that (although as I've just
noted in another reply, that doesn't seem to work for me).
There appears to be a compulsion by users to complete tasks in
Maproulette even when they have no *accurate* knowledge. This is
wrong. It adds *erroneous* data to OSM.
There's a clue to Maproulette's randomness & uncertainty in its name.
I believe a good way to improve OSM data is to ban Maproulette.
There are a number of these sorts of tools around, and to be honest
(with a DWG hat on) I see fewer issues raised about Maproulette than,
say people using HOT's tasking manager and not knowing what they are
doing (not usually their fault - it's almost always due to not enough
suitable training). Maybe people who use Maproulette have an idea of
what OSM is and are already familiar with one or another editor and
maybe that isn't true about some HOT mapping.
The only recent Maproulette issue I can think of where dodgy POIs added
via MAPS.ME had some extra "missing" tags added via Maproulette. The
task in Maproulette should really have included "check that these things
added by MAPS.ME users weren't mistaggings or just personal markers",
but that's really something that should be in the task definition
itself. There's a discussion about a general "form of words" over at
https://github.com/maproulette/maproulette2/issues/348 - that, together
with the availability of "false positive" and "skip" buttons should
allow people to only contribute sensible data.

Andy
