Hypothetically speaking, if X was to know the name of person Y, how would X go about digging up personal details such as phone numbers and addresses online.
Asking because I saw a film (a while ago) where the hero goes online and find this info on a villain after knowing their name.
A long, long time ago, there was this thing called a phone book. Everyone who had a phone had their name, address and number published unless they were willing to pay a fee to keep the number unlisted - few people did so. In North America, you can dial 411 and ask but there is a charge.
