I've been getting a couple of these each day for the past few days. It's always a bit entertaining. Partly because my email address is my name (so I know it's not likely a typo when folks enter the email address). Partly because I leverage GPG from the Facebook side so the messages are encrypted.
Meaning, even if they somehow had access to my email (they don't - strong, unique password and separate MFA) they wouldn't be able to get the reset code as it's encrypted by a key stored in secure physical hardware.
Still, kudos to the hackers for trying. Getting these emails means _someone_ cares enough about my account to want access. Even if I rarely use it for anything other than checking in on distant relatives ...
