Ads are successful everywhere. The size of facebook's userbase helped its ads reach a lot of people, but the number of facebook users has been declining while the old folks staying on the platform grow ever closer to death.

Facebook has done nothing but demonstrate that it's a company which doesn't care at all about its users and is willing to hurt them. Anyone still using facebook at this point is pretty much asking to be taken advantage of and abused. I rally can't feel bad for them anymore.
