Real life is hard
Too many loopholes in these policies, because you need to define a political ad. As FB now understands, you can't do that by looking at the message, only by the status of the advertiser. But even that is full of traps. You are a formally registered political candidate ? No ads for you. Easy! Let's go to lunch. Oh, but wait. Which of these are in scope
1 I am a FRPC, for election X. Can I advertise in concurrent election Y ?
2 I was a FRPC in election X last time round but not this time. Can I advertise this time ?
3 I am an employee of a FRPC campaign and wish to advertise as a private citizen ?
4 I am a FRPC for a legally established party that is campaigning on policies based on proven lies ("bacon is evil, we will ban bacon"). Going to run my ads ?
5 I am a lobby group, NGO, charity. Can I run an ad unambiguously supporting a FRPC ?
6 I am a single issue lobby group, NGO, charity. That issue is supported by only one FRPC. Can I advertise ?
It's almost more honest to ignore the dishonesty and just take everyone's money.
