Frederik Ramm now has an overview map of the objects actually deleted and modified by the bot.

Great! Thanks a lot! That's pretty much the kind of visualisation that I had in mind. Now if there would only be a way to know which keys have been modified or deleted (not the exact values of course) and which relations have been broken.

Has any of you succeeded in using the underlying WMS inside JOSM:

I (quickly) tried to get it to work and found the list with the various layers, I adjusted some parameters like FORMAT and TRANSPARENCY, but I kept ending up with error tiles. I'm not sure if this is by design of Frederik (to prevent tracing) or simply due to an oversight of me.

For the areas I know and fixed already, it seems to be working pretty well. I just came across one deleted road that it didn't catch:

This road was also missing and had to be redone (the only thing left was a set of orphaned nodes):

But it doesn't show up on Frederik's map:

Again, that was just a quick check, and I can't tell if this is really a bug or just an oversight of mine, e.g. the road was deleted by someone else.
