@Kipawa:
FB found a way around advertising animals. Shame on them. Maybe if all of us contacted FB and told them we would dump our accounts? The FB person who gave the go-ahead for this type of advertising should be very embarrassed. Animals are not commodities!
FB did not create this advertising. They bought, or made some kind of arrangement with, an existing advertising place called Oodle. It is basically the same thing that Ebay did when they bought, or made arrangements with, an already existing advertising place called Kijiji. Both companies took advantage of using already successful "businesses" to advance themselves. A smart move from an investment viewpoint.
I don't understand why people would object? It is pretty much the same as the classifieds section of a newspaper. The only difference is that it is online instead of in paper form. Having the advertising connected to FB accounts can be very advantageous to small, family businesses. Let's say you make jewelry and sell mostly on etsy. You can promote your items on FB with links to your etsy account but if you can post ads on the new FB marketplace, you increase your advertising by potentially reaching millions of more people. The advertising potential is also advantageous for finding homes for animals. Yes, most ads are from irresponsible breeders but responsible breeders and rescue groups can possibly find homes through there also. I see this as a good thing.
