Tech Q&A: Hide your Facebook profile, hotel Wi-Fi, and more

Q. I’m a corrections officer and I’ve gotten some friend requests on Facebook from former inmates when they get out of jail. I want to keep in contact with my family, but I want to stay hidden from everyone else. How can I make myself invisible on Facebook without deactivating my account?

Go to the lock icon at the top of your profile, and under “Who can contact me?” change “Who can send me friend requests?” from “Everyone” to “Friends of Friends.” This should filter out your work problem. You can also change your message filter in this area to strictly filter out messages from people you don’t know.  More
