It's pretty bad. HIV clinics have "no-contact" lists and if you hypothetically worked for a survey company that made a phone call to one of those numbers, and said you were calling from "XYZ clinic for PQR person who isn't here right now", and the person who takes your call connects the dots, and realizes XYZ clinic is an HIV clinic... you could make two people very upset, and one person homeless. Hypothetically speaking... it could be real bad news. Let's just say after that, we asked every medical office we ever worked with from then on, if they had any "no-contact" lists to please ensure they remove those people from the contact list before we started making calls. We had a mail/phone operation and I'm just imagining our production manager not looking closely enough at even one of 12,000 pieces of mail in windowed envelopes that says "HIV medication" in plain view, before loading them into his car and mailing them at the post office. He'd be canned instantly. Someone definitely got fired over this.
