FB sends me an invite to try out an ad for free for my new book cover. "Free $10 credit" it says. "Click here to boost this post"
I say okay, and then I get a message,
Then I get another message saying,
And when I look at my "free" ad I see they are asking me for money.
Honestly. Lure me in with free stuff, then snatch it away, threaten me and then demand hard cash.
Facebook would be right at home with the Zeta cartel.
Update: 23rd August 2017 FB wrote to me to say, "OK, you can advertise" I suspect a trap...
