Ancestry DNA is even worse than this. I heard someone who wasn't recognised his French and German heritage by them. On the other hand, they assigned them Southern American, Turkish and Moroccan ancestry, despite having none of it in at least six generations, according to their family tree.
I would not be surprised this was the case, but nobody is going to legitimately admit it. They say all samples are "Regional", in their methodology, and this in itself admits the lack of accuracy is pretty high, but also a political agenda of fighting "Nativism". One of these sites, even said that their "mission" is to show people how everyone is essentially mixed, ie, they had a political reason to do that.
20 years from now, if many Moroccans live in Paris, who are "sampled", they will label them as "French", and then claim that France was actually Middle Eastern all along or something.
One similar scandal was the company Theranos, this jew on Theranos was selling fake tests for cancer patients, unimpeded for years, until it could go no longer. They denied responsibility for years, even after the courts went in.
I wouldn't be surprised if people have literally sent animal DNA here, and it came out as errant, or they cared not even to do a proper analysis, as most these companies do, is propaganda.
Regardless, it would also not be advisable for people to send their DNA there, because they are trying to form a DNA bank regardless of this.
