So yeah just be aware if you get an email that has your own display name as the sender (and a random email address that's almost certainly spoofed) as well as one of your old passwords (probably one you've used before but already changed as a result of it being in one of those data breaches which is basically publicly available), claiming to have keylogged you using a porn site and hacked your webcam and display, and contacts, it's fake. They're trying to scare you into paying bitcoin. Ignore it
@Nine Video of someone watching porn is fairly uninteresting anyway, unless the person happens to be sitting far back enough, is talking to themselves, and/or it includes a screen recording. ¯\_(ツ)_/¯
@faoluin supposedly it does have a screen recording too, but it's definitely false. XD I don't have a webcam for a start and it claims to have gotten my facebook contacts (I don't, and have never, used facebook at all. don't even have an account... i mean facebook probably still has details on me regardless of this fact, but I don't have an ACCOUNT on it, so...)
Oh and don't reply to it at all, or click any links in it. MAYBE screencap it, send it to whatever phishing report system you can, or find one of those bitcoin wallet lookup things and report it for scamming like I did I guess (I don't use bitcoin, I never will, and I have no idea whether it'll do anything but hey why not), but otherwise just ignore/delete it forever. It's not real, it's fake.
