It's been going on for months - if you're not aware of this it doesn't mean it's not widespread. If you tweet "metamask problem", you'll get a number of bots immediately responding with Google forms links for "metamask support". Yes, it's very widespread and extremely obvious. Both fake support accounts https://twitter.com/metamesksuport/with_replies (I can find at least 10 more "support" accounts from a basic search) and helpful randos https://twitter.com/ij851227/status/1515302472079847425

It's been tweeted by multiple security people at various Twitter engineers already and raised in lots of ways. They know and don't care. Meantime, real people lose their money - otherwise nobody would waste their time to post the scam.
