As the original thread reached the maximum 100 posts, I start a second one.
The changes for OK are already visible: Either download https://www.sotadata.org.uk/summitslist.csv
or switch the summit icon to activation count in the SOTA Mapping project. All summits pending deletion have a brown ring. Also hovering over the summit in the summits listing on the left gives an indication. Here the reference in the popup is on red background.
It looks as bad as expected. Scenic summits like OK/PL-023 are deleted. Walking the 4 km from my favourite starting point, I could swear this is a mountain. Another proof, P150 does not really work for the low mountains in Europe - but who cares?
Condolences to the Czech activators.
