That's why we have an import policy. Most of the problems I have seen with imports would be prevented if people actually followed it.

Still having said that there seems to be a large number of Buildings mapped in Africa at Mapathons that seem to be of poor quality and if it was better than that the over all data quality might improve.

In Canada my understanding is some sort of automated or semi automated building outline mapping is being done by NRC and will be released shortly under an Open Data license that has been approved by the LWG.  These I might trust, an experimental algorithm on less than perfect imagery I might be more wary of.

Mapbox has indicated that they are also on board  (with some conditions/restrictions). I think this pretty big deal for OSM. If you are interested in this kind of stuff, I wrote a longish diary entry about what it might mean.
