Ai impersonation paid ads on Facebook are a big problem

It’s usually an ai dubbed voice of an influential figure on a poorley edited video of him/her moving his/her mouth promoting a snake oil medicine for knees and joints pain,clearly the ads are targeting older people who have less tech knowledge i don’t know if this is a universal problem on Facebook or is it just a problem in the arabic content caused by lack of moderation in the middle east, Note:iam speaking about official paid adds from the site and not just posts (and sorry for my english)
