And? We are already tagging official garbage dumps, why shouldn't we
tag unofficial/illegal/informal ones?

I feel that in this topic there is big cultural differences. While
some people say: go to the police / court, others see the
necessity/wish to tag them in OSM. Why should we hinder them? Some of
these issues I couldn't believe them myself, but living now in a
country, where even in the third biggest city the garbage is
frequently illegally deposited in the settlements/suburbs (e.g. see
here http://www.newnotizie.it/wp-content/uploads/2010/12/Rifiuti-napoli.jpg
or search pictures for "rifiuti napoli") I am beginning to understand
the desire to tag this stuff.

Maybe it is the wording "illegal" which creates opposition? What if we
called it informal? I already use informal=yes for paths, but it could
just as well be extended to garbage dumps and a lot of other stuff.
The common word in Italy is "abusive" (would this work in English?),
and it is used for everything from people (immigrants without formal
documents / rights to stay) to houses (built in nature reserves or
other zones not declared for constructing and/or without building
permission and/or with clandestine employment and/or more then
allowed) to garbage dumps, fences and so on.

Martin

The power line voltage is gleaned from signs, which is how we get many
of our features. I only know what street I'm on based on the sign that
tells me so.

If there was an official sign that said "Illegal dumping, 300m", I'd
be more inclined to listen to this proposal.

How many of us know what a street is other than by official signs?

Your argument about smoothness is why people prefer to know the road

This case is perfect, since it illustrates that you're basically
deciding something you feel is suspicious is illegal. You have no idea
if that pipe is there legally or not.

My point was that "dangerous" was rejected as a tag. It's just too
problematic to use.

Peter> That's for the courts. But we can tell other walkersby about it.

No one's arguing that there may not be value in the data you want to

lot of useful information that's not appropriate for Wikipedia.

This is a fair criticism. The problems with this tag are that it's:

1. Far more subjective than other accepted tags
2. Carries a lot of weight. It's a serious thing to accuse
someone/something of being illegal.
3. Libelous, in that this is an accusation.
4. Outside the scope of the project, unlike any other tag we have.
5. This tag seems to beg for an edit war.
6. Apt to change very frequently.
7. Activism/advocate. OSM is not advocating positions. That's why even
in the case of political borders, there's sensitivity in how it's
handled.

I think this data belongs in another dataset- not OSM.

What OSM does care about that? We tag the illegal dumping, so people

Why do we care if it's illegal? What we would care about is that there's

You have your decision making in your head. Why would you tag it as
illegal? For example if I see a concrete pipe which clearly 100 years
old I wouldn't, but when I see one hiding under bushes and clearly
built this spring I'd say it's hardly "legal", and I would give good
chance to courts say the same if they would care at all (which they
really don't, mind you).
If it's hiding under bushes that may be for visual mitigation purposes. 
It may very well be legal in many places to dump bad stuff into water, 
especially if that water is a closed basin or upstream of some beefy 
filtering equipment. As I said above, a theoretical swimmer doesn't care 
if it's legal - he wants to know that there's something bad there, 
period. So hazard=factory regularly dumps benzene in water is much more 
useful than illegal=yes (and more correct if the dumping is legal).

In general, I'm also against tagging what is not physical and immediatly
"verifiable" attributes. But hey, the idea of indicating the legal status is
not worst than many other tags already widely used. And it is verifiable,
not easy but it is (not less, for instance, than the power lines voltage).
My concern is more about the tag name itself. We fall in the same trap as
the disused=yes. It has the advantage that you don't have to set any special
rules for renderers but you also take the risk that many data consumers will
ignore this status and consider the object as 'usable'. We have this problem
with disused railways or roads. We will have it for illegal dumps, illegal
constructions or illegal business.

First, it's not simple and measurable, at least I really wonder how
many of us measured an incline which isn't signed (I have tried, takes
time and a bit of math, and I don't even play it for most of the
cases).

Second, both, but especially smoothness (and all subjective tags,
since I personally find smoothness very useful and informative)
depends on the judgement of the mapper. I think it is normal to expect
mappers to have common sense and good judgement, which is the base of
all the mapping activities anyway. We usually decide what's a track
and what's a path, whether a road is service or residential or simply
unclassified, et cetera. All are pretty subjective.

And third: they're not "physical objects", they are attributes, which
was my point here.

Indeed similar. And I agree in both that it cannot be measured (like
smoothness or grade type or mtb grade) and there is no easy way to
standardise. But I do not think this makes it somehow exceptionally
unusual in the OSM environment.

Such "blocking" comments are not really very cooperative. If you cite
those so many reasons they might be accepted or rejected, but nobody
can help you with those theoretical "so many reasons". I've heard very
good ones against the tag, and some which simply required a bit more
specification, but I cannot do anything about the "so many reasons"
you just mentioned. :-)

(Of course it's probably not useful to reiterate that what's been already said.)

The original comment stated a theoretical problem which I may find
very unlikely to happen, and I believe it's probably the same
probability that someone (like a local gov't official) gets offended
that his pet road was called "horrible".

And again, you have been ignoring my comment about wording. If
"illegal" have the strong connection to "law" then please help me find
a word which conveys the same meaning but in the common sense view.

What OSM does care about that? We tag the illegal dumping, so people

If court decides its not illegal then great (if we know about it), we
remove the tag, even can reference the decision, and we made the map
better. If it was illegal then, hey, we were right.

The puspose is not to attribute that law decided something is not
legal, but to attribute things which are not what thy look like, or
things which shouldn't be there, etc. Again, you're most than welcome
to fix the wording.

You have your decision making in your head. Why would you tag it as
illegal? For example if I see a concrete pipe which clearly 100 years
old I wouldn't, but when I see one hiding under bushes and clearly
built this spring I'd say it's hardly "legal", and I would give good
