I'd be curious to know how well that's enforced. There's an ocean full of HR tech startups that are doing just that programmatically, to produce scores on all sorts of things to rate candidates.
Sounds like all those HR tech startups would violate GDPR in Europe and they should be fined out of existence.
If you want to hire people, look at their CV and talk to them. Don't go behind their back making judgements based on websites, facebook profiles or reddit accoints that are likely to be wrong.

No they shouldn't. What they should do though is geoblock all access coming to their sites and services which they can identify as coming from EU origin, plus add to their site EULA that anyone under EU jurisdiction is not authorized to use their site under any circumstances and such access will be considered unauthorized access, which is a criminal act.

That's two of the most likely sources of lies. Neither has much value.
