We have public records with name, address and phone number where i live. If you don’t want to be searchable in this registry, you just login to citizens self-service (or go to townhall if you don’t want to/can’t do it yourself online) and select that you want “secret address”, and your info is purged from the list. No need to go through weird and semi-sketchy third parties to get it done. I’m not sure how other EU countries deal with this.
