So the real number of those domains is likely to be much much larger if you would have the same dataset like crimeflare had. You can find articles about it with the keyword "Schattenwebsites lieferando" because that's what the press seems to have settled on. Different press teams counted different amount of websites because of that. Another team where I knew people from the CCC that helped them confirmed the 120k number though.
Our final number in Q4 of 2021 was 130k domains that we found out about, and we were trying to contact a bunch of other business owners to be able to escalate the lawsuit onto the Landsgerichtsebene (so that it can go into the Bundesgerichtshofsebene afterwards, and then to the EU court).
