Hi Simon,
I am not sure what you mean here, can you explain what you mean by ‘I doubt that something has gone wrong’?
To my understanding the redaction should have brought the nodes and ways back to the state from before the copyright infringement. For the sample of buildings I checked that state was being a rectangular way tagged as building=yes and thus also 4 nodes. Now the way has three nodes, and thus is a triangle. To me and probably most others this looks like a unsuccessful redaction.
Cheers, dikkeknodel

I doubt that something has gone wrong. A redaction is not a revert (aka it doesn't restore a previous state of an object), so the result depends on what happened in the changeset that is being redacted.
If a building was added then it will simply vanish, if the geometry was manipulated (for example by removing and adding a node) the results might not be what is "expected".

Hi all,
I had a closer look at the naoliv’s redaction CS61021881.
I see, many previously rectangular buildings have now become triangles or just an open L-shape.
https://www.openstreetmap.org/way/317495841
https://www.openstreetmap.org/way/317495891
https://www.openstreetmap.org/way/317487442
etc.
More complex shapes have also lost a node and became less complex with some very weird shapes.
https://www.openstreetmap.org/way/317487614
https://www.openstreetmap.org/way/317336799
https://www.openstreetmap.org/way/317336826
etc.
It is all over the place basically. If a look to the pre-redaction version of the buildings, they seem to be nicely rectangular.
It also seems that the address data entered with CS60359203, CS60359697 and CS60359350 have been (mistakenly) redacted (the blue ones in achavi, tag change only). These CSs mention local knowledge as source and there is no mention in the changesets discussions of any problem.
Something seems to have gone wrong with the redaction is my conclusion.
Cheers,
dikkeknodel

Hello,

I think the latest changesets from user 'naoliv' are erroneous. Can somewhere check and maybe revert this? Thanks.
can you give an exemple ? naoliv redact (hidde) data copied from Fribourg cadastre (the licence of the canton of Fribourg doesn't allow it). so a building should not be corrupted by this redact but it should be already corrupt before.
are you the guy that did the import ?
