Hello Alexk64 and welcome to OpenStreetMap!
Andy from OSM's Data Working Group here. A couple of users have asked about your changes around Fawley. You can see the comments that people have left on your changesets at http://resultmaps.neis-one.org/osm-discussion-comments?uid=12279940 (and these will have also been emailed to you of course).
As as been mentioned to you, the roads within the refinery are surely not "primary" roads in OSM terms. Here's a map showing roads down to "primary" in southern England https://map.atownsend.org.uk/maps/map/map.html#zoom=8&lat=50.946&lon=-1.956 and that red splodge at Fawley is clearly out of place when compared to mapping elsewhere.
We'll need to change these back to service roads at the very least, but there are also some other questions:
I notice that you've deleted the communications mast https://www.openstreetmap.org/node/4289385507/history that was previously at https://www.openstreetmap.org/#map=18/50.83144/-1.36126 . Was that deliberate? If it wasn't, we'll probably need to undo more of your changes.
Andy Townsend, on behalf of OSM's Data Working Group
One more thing - if you'd like to get in touch with other mappers, to ask them about things, you can read https://wiki.openstreetmap.org/wiki/Contact_channels . In this part of the world the two main channels are probably the mailing list https://lists.openstreetmap.org/listinfo/talk-gb and the #osm-gb IRC channel - see https://wiki.openstreetmap.org/wiki/IRC for more details about that.
