Thanks for your hint Oliver 
Yes, indeed I know OSV, but expected it to be more something like an open Google Streetview replacement. To be honest I didn’t knew anything about the moderation or bluring features.
I know it’s not very popular on OpenSource projects just to say, “what’s missing” instead of fixing itself, but a few things came up to my mind, when I played around for 5 minutes and remember my experience from the 3D senario:
Privacy (legal)
Esp. here in Germany it can be difficult to say definitly if something is legal or illegal concerning publification of media, that might touch other peoples privacy. In short: The problem of saying yes/no might be undecidable
and maybe it’s just accepted to life in this greyscale zone, as the mass of standup photos at social networks show…
But currently we had absolutly no problems, as we didn’t publish them (see user:Falcius talk at FOSSGIS2011
Privacy (emotional)
What makes OpenStreetPhoto.org better? It just doesn’t sound like the Google Streetview service, that got a lot of troubles here (starting with a lawsuit, as they sniffed WLAN traffic and finally villages, that prohibit to get recorded. Even if this might be extrem behaviour, it should be respected, esp. from an open project, that benefits from it’s underdog image.
Here the only example from my town Rostock

As you can see it shows the car license number. Here it seems to be legal, as there is no really bad context (say in front of a brothel, or a police car or showing the drivers face). But what about the driver? What would you think, if you or personal things show up at the internet without any permission or at least a hint? Difficult from an emotional POV 
Other legal problems
It becomes more difficult with things like copyright, even for the person who takes the photos. Maybe the artwork or the architecture of a building was protected (good explanation in german)
I have no plan how it could be realized, just a few ideas of what seen elsewhere
-allow reporting an image as conflict (“I’m the one who is at the photo”, “I’m somebody that expects problems at this photos”, …)
-don’t make them public/copyleft by default, but allow people to ask for it’s “liberation”. Per default allow only the use for OSM and point to the law in the country.
-people from the same country should be moderate an image (as they might know more about local law)
–offer wiki pages with recommend moderation behaviour per country
–“ask a lawyer”-button that might delegate the moderation to users that have legal experiences
Usability
-tag them for 3D, to get found by 3D artists
-link/group them to OSM object or Wikipedia entry or at least to a single name
-share permalinks (e.g. for requests on OpenBuildingModels)
-step by step process is clever, but need to be explained e.g. how can I put my photos at the map, if they don’t contain a GPS tag?
-setup direction of the photo?
-some eyecandy at the UI
Use of photo material
For 3D/micromapping it’s mostly interpretation and photogrammtry (reconstruct geometry, use as texture) and both might require differnt resolution. So not every webcam image might be good enough 
Please, don’t misunderstand me. OSV is quite nice! The FTP upload is brilliant and I like concept of peer reviews
