You can't post photos as a newbie, but you can still show us the link to the screenshot.
I haven't received any message like that from MetaMask, so it's likely that your browser data has been infected, most likely from a site that uses MetaMask that has disguised a user opt-in form (or similar) method to capture/phish your data.
From my understanding, MetaMask doesn't provide account support if you lose your seed, so it would surprise me if they actually did send out some form of warning.
Edit: Actually, wait... Since when does MetaMask require KYC verification?
Sounds to me like you're on another website that accepts a MetaMask plugin that is trying to phish information, not on the MetaMask site itself...
