> We used to spend significantly on Facebook for several businesses I'm involved in, but now that most clicks are garbage/fake, we don't.

It seems to me that the rational reason to stop an ad campaign is because it stopped enough making money.

It's not fake clicks that should be stopping you -- it should be a lack of ROI.

I wonder how many people spend huge sums of money on Facebook without tracking their return on investment. I seriously think that is the source of many of these complaints about Facebook's ad program.

I spend a few thousand a month of Facebook. I have no idea if there are fake clicks or not. But, it's not a metric that seems to matter in my business.
