Hi Jurgen, adding it to OSM could make sense, yes, thanks for thinking about that! I have some more questions though:

Have you taken a look at the Automated Editing code of conduct in the mean time? OSM is pretty free, but we're quite strict on mechanical edits like this. I invite you to still open the prescribed discussion after the fact.

For instance, one question I would have in such a discussion is: Do you check this list to avoid false positives? E.g. spa.be is for the water, not the city. Spa already had its real website, which you luckily didn't overwrite. But there could be others like this.

As Joost already mentioned, your edits have been corrected with a (correctly working 😛) script of mine. So the added websites have been retained for now, since I hope that everything will just work out once we have a friendly talk over this.
