To quote the official FAQ of OSM:
"The essence of a wiki-style process is that all users have a stake in having accurate data. If one person puts in inaccurate data, maliciously or accidentally, the other 99.9% of people can check it, fix it, or get rid of it. The vast majority of good-intentioned participants can automatically correct for the few bad apples. "

We hoped that our donation would be of good use for the OSM-project. I thought that this was a Wiki-project, just like Wikipedia, were everyone is free to add or remove data.

CoryBurger: I'm sorry if you feel that we have destroyed your project. We have a lot more data - ready for donation, but we are not sure if we should upload it.
