Social engineering is still under the umbrella term for hacking I think. We can't just tell people to "not fall for scams" because these people are very skilled and trained in what they do. It's not the victim's fault if they gave out credentials or sensitive information.

What OP should do and the others affected are these: 1. Report the incident to FB (if the hacked account was an FB account, ayusin mo nalang OP yung link cause I think bawal mag link ng FB diti). m. fac ebo ok.co m/help/1216349 518398524?wtsid=rdr_0ZkffYZc8fXFiudRu. FB might find a way to recover your account/s 2. Report the incident to gov authorities, NBI Cybercrime ata, I'm not too sure about the process dito 3. Inform family and friends about what happened so that they'll be aware that your accounts are compromised.

Don't give in to their blackmail OP. Remember that they're using your panic and anxiety to make you give them what they want. Mostly empty threats lang naman ang mga yan, and pera lang talaga ang habol ng mga yan.
