Without wishing to blame any WSPR operator, I am having some difficulty understanding how the reporting of WSPR 'traffic', between two stations separated by minimal distance, actually helps anybody understand radio propagation. In this case the stations are listed as being 0km distance. The effect is that huge signal levels are reported with a lot of phantom decodes, making the whole process quite meaningless. Perhaps there should be some kind of filter so that these results are excluded from the WSPR database so that any statistical analysis is not invalidated. Without such a filter, it looks like a bad case of 'flooding'.
