Is posting an address and someone's # on a commercial website illegal?

I work for a realty agency and they have a website which they fill by looking into ads in the paper and driving around looking for "Rent" signs to post on their commercial website. They obtain the address and phone # either by acting like a customer or by stating that they are a realty agent. They charge people who are looking to rent to look at their full listings of apartment and for services. However, some of the Landlords don't know their info is on the site. Legal or Illegal?

yes it is illegal and google can ban your website for this or penalized your website.
