They can't and won't, anyone savvy enough can obfuscate it enough. This is just fear mongering for the masses, in other words, business as usual for the government
I would do this before I deleted my Facebook account when I ran ads not to intentionally exclude people but because I figured people over a certain age probably wouldn't know the technologies I was looking for and I figured I would probably end up paying for false positive ad clicks
Yep. I was hoping that sentence would end with "because I figured people over a certain age probably wouldn't be interested in entry-level positions," and I was prepared to think that was an interesting point.
It is factual that certain technologies are more used by certain demographics. If someone has a very small ad budget I don't understand why they should be forced to display ads to a demographic less likely to know the technology.
No, can't really be the case that they can't rather they would just have to be too ignorant to do it elsewhere, if you can buy Bitcoin it's relatively trivial to buy any other crypto currency.
