Advertising on social platforms turns your users into commodities. Unless it is informed consent this appears to me to be highly unethical.
The best advertising I have seen recently is companies sending me sats with memos saying "Hey, please try yada yada! Thanks" this is the first direct advertising that actually inspired me to consider a product.
