Has anybody done Mass Dm's for ecommerce or dropshipping?

I ran a ton of ecom stores in the past with paid traffic. ad costs going up + Fb ad account bans have made the business really hard to be profitable. Looking into blackhat methods to continue running my stores. Has anybody done mass dm's on ig/fb to get sales? If so can you please point me in the right direction on where to learn more about this/how to get started. Would also be happy to pay for consulting. Thanks

I haven't, but I am interested as well. Will test any services
