A register, not a rumour mill
Register R-01 will list sites the Survey has been asked to look at, sorted by how far you are from them. Your location is used on your device to sort the list, and is not sent anywhere.
It is empty because the Survey will not list a site it cannot source. Most lists of this kind are copied from other lists of this kind, and the further you follow them back the less there is: a name, a date that does not check out, and a story that first appears in a newspaper column from the 1970s with nobody attached to it.
Every entry here will state where it came from — the record, the report, the local history, the newspaper — and where the trail stops, it will say that the trail stops. Some entries will be more interesting for having a bad source than a good one.
That takes time, and it is why this page is empty rather than full.
