My new office required us to make facebook account to promotional purpose, and 2 days ago i made new one with my real name and everything is real, i just dont upload the photo yet because its on office PC. A few hours later when i open facebook to upload the photo i am suddenly log out and there is message "We've noticed suspicious activity on your account. To get back on Facebook, we need you to provide some additional information." i press the continue button and they ask for my photo and i upload it and another message appear "We'll check it bla bla" and until now i cant access my facebook.
I don't understand, What does suspicious activity mean? does is mean someone else trying to log in with my account ? I think its impossible because i just made it. And i am thinking about phishing malware but when i scan with Malwarebytes free and avast free everything is clean and nothing suspicious.
I read on internet this happening because facebook think this is fake account/bot or etc, so they send suspicious activity warning. Is it true ? What do you guys think is this because someone else try to hack my account or this is from facebook because they think my account is fake/bot?
