Facebook’s statement mentioned, “We hope the people in the area of the bombing find Safety Check a useful and helpful way to let their friends and family know they are okay. Unfortunately, many people not affected by the crisis received a notification asking if they were okay. This kind of bug is counter to our intent. We worked quickly to resolve the issue and we apologize to anyone who mistakenly received the notification.”
Facebook CEO Mark Zuckerberg did say the following as he launched the Safety Check in October a couple of years back, citing it “as our way of helping our community during natural disasters” with the idea of providing users with “an easy and simple way to say you’re safe and check on all your friends and family in one place.”
