I occasionally visit a local medical complex and I was pleased to see they now have free guest wifi. On my last visit I signed on, agreed to their user agreement by checking “accept”, and happily used their bandwidth while I waited.
Yesterday while parked outside one of the tenants of this complex I received an email suggesting I might enjoy the services this tenant provides. As it is a business I would never visit my conclusion is that by my using the free wifi, my email address was harvested without my consent. The tenant uses the same internal network as the medical complex.
On reflection I am guessing I probably consented when I clicked on “accept”. No, I did not read the agreement before I accepted.
