I was getting about a dozen or so messages and emails a day after I responded to a post in another group saying I’m running ads for a client who is supplying EQUIPMENT to companies making masks. Google will shut you down, they won’t even give you a chance once they find you are trying to profit from the sales of masks. I’ve even heard of some accounts being suspended over having masks for sale on their site, yet not advertising them. There’s a few loopholes with other products, as well to advertise on FB and other networks, but it’s an uphill battle
