I did this once when someone created a Facebook account using my address. I let it go for a year and then did a password reset and deletion. At the time there was no requirement for email verification so the account was fully functional. Again, this is Facebook's responsibility to verify new accounts. A confirmation email link is last century's technology.
Moreover, what happens if this doppelganger is committing crimes via said account and investigators track you down from the email. It is in your best interest to eliminate these accounts. Kindly explaining the situation to non-existent customer support will get you nowhere.
IANAL but I don't think it works like that. Ownership is not the same as control.
Yeah, no. Peace out dude, I'm done here.
