These sero studies he mentioned where low quality studies. His study used Facebook ads to get participants (which isn't randomised, fb algo is showing the ads to people who are likely to click) and then he "corrected" the sample by income which isn't questionable but simply a wrong practice. A randomised sample doesn't has to be "representative" and a quota sample won't provide conclusive results. Other serology studies pretty  much disproved his allegations. That said in the beginning people definitely overestimated death rates everywhere but corrected that as the pandemic was ongoing of course.,(reply>), @——————  he praised his own studies as high quality like he did elsewhere. At least thats what I got. And it's unconclusive with the wrong sampling which equals to useless unfortunately.,(reply>), He said that. Low quality does not mean not useful. It should have been health authorities doing high quality studies. But they didn’t.
