One in five of us secretly snoops on our friends' Facebook accounts

Minding other people's business: Using mobile phones to snoop was more common among younger people.

For their research the team surveyed 1,308 US adult Facebook users and asked them to answer questions on their behaviour on social media.

After gathering the responses, the researchers estimated that 24% of participants implicitly identified with the statement "I have used a device of someone I know to access their Facebook account without permission," snooping on their friends, romantic partners or family members using the victims' own computers or cellphones.
