For the last few weeks, I’ve noticed that I’ve been getting an influx of spam calendar invitations to my iCloud account, often from random counterfeit retailers. “Save 20% on UGGs” one says. “$19.99 Ray-ban&Oakley Sunglasses,” says another. I’m not the only one. Users across the web have complained about this influx of spam. The New York Times even covered it. And when The Times is on it, you know it’s a real thing.
