Actually I don't mind that, because if you want to survive you have to do something, but this is too much. First of all they use people as commodity and then charge advertisers too much to advertise, plus on top it lies about ads. Please see the pictures below for proof.
The way they have presented I should have got 2.9k to 8.5k likes, yet I only got 304. Can you believe that? Ok Forget that, I've spent £41.00+ yet I only got 3,125 likes. That means it's totally useless. I've also noticed that if I don't promote they don't promote my posts, that means it's forcing small page owners to boost (paid) their posts so that they can grab more money. By losing over £40+ I came to the conclusion that Facebook is not a place to advertise. It might be good for few but most small business will loose heavily without gaining much.
I've tried many things to be successful in life but failed everywhere and this is another one in my book.
