This was me, but I know that Paul Sladen, Simon Halsey, and probably others, were also affected.
Has anyone has sent the offending user a message? He/she is a relative newcomer, and has edited in Trowbridge as well as Carlton/Gedling. They have also edited in Germany, but no indication of traces or on-the-ground surveys. Some of my GPS ways unfortunately also had fixme=location approximate, which was probably as a result of over use of copying tags from one way to another. This may have invited editing, but other 'corrections' have been made so that now many streets are slightly misaligned from GPS traces. I, and I would guess other active contributors around Nottingham, have been avoiding using StreetView and Locator other than to add names on stuff mapped from aerial images. In particular the Carlton/Gedling area is one which my personal preference was to leave the current status "as is" until ground surveys were done. Obviously other contributors have different preferences, time-scales, needs etc., so I recognise that this might not be possible. I would hope thought that some contact with active local mappers would be made before bulk in-fill with StreetView or similar sources, particularly as it cannot have escaped their attention that this was possible. Last Summer I mapped a tiny part of Middlesbrough over 2.5 hours. When StreetView became available an area about 25 times larger was mapped in a similar timescale. The 'productivity' difference is so huge that a single armchair mapper can swamp contributions from people doing ground survey. On the other hand, places like Oldham, Rochdale, Darlington, Middlesbrough are now so much more usable in OSM. So we still have the trade-off between usability of the map data, contributor 'happiness', mapping from an armchair versus on-the-ground. The use of StreetView exemplifies all these issues.

Please, please, please, pretty please don’t just assume your data is better than the existing data, especially if yours is derived from another source and the existing data is from a ground survey.
