FB makes reaching out to their support a pain in the ass. Since I was somehow able to get in touch with someone, and I collected what I felt was decent evidence that this is happening, and I was actually able to show that evidence to them, I figured it'd be worth putting something online as an additional warning to others not to bother advertising on FB, and, more importantly, speak up and call FB out on this mess.
Isn't that fraud on behalf of Facebook. You're paying them to present the ads to people who have characteristic A, but they instead show them to other people and charge you as if they'd done what you asked? Or are all those people saying in their profiles that they speak Hebrew? [Which makes it just people lying and not fraud at all].
Each time I got a (very) large amount of likes from Palestinian and other Arabs who most definitely don't know Hebrew, or English, or interested in tech. Most of their profiles have thousands of friends, and everything is written in Arabic and not English/Hebrew.
For the last 4 years I tried putting small amounts of money to see if the situation has changed, and each time the result was very similar.
I didn't go and talked to Facebook support about it, since that would be a waste of my time imho, and not do any good. The support engineers with canned responses most probably cannot do anything to change the situation, or even if they have ideas for improvement those would be drowned in the huge FB ocean of outsourced employees.
