Yes. I always bring this up when people in forums start talking about using these scumbag food-delivery operators.

Not sure about phone numbers, but some of them were creating "websites" for restaurants.

It is so ridiculous how that works. Just imagine for a second that you make a lieferando fake website and bring that online and somehow manage to make the URL look alike. How quickly the lawsuits would be on your ass. Yet according to one of the top level comments, nothing is done here, when lieferando does this and even throws in some identity theft.
