This article popped up on my news feed and as I don't remember seeing it mentioned elsewhere on FTLA just posting for information (apologies if I missed it here).
Seems there's been a growing number of fake PCNs put on cars purporting to be both Council and Private, inviting you to click a QR code to pay. Usual scam, they want to steal your card information and ID details.
One giveaway is that reportedly they don't give information about rights of appeal to POPLA/IAS. And presumably ignoring them can't result in an NtK.
