All good points, and I was sort of coming at it from the point of view of catching cheaters. ofc cheaters skew the data but theyre ultimately hurting themselves. They wont pass a companies' entrance tests or will soon find themselves unemployed if they cant do the work. Yes its a problem but I see a lot of effort being spent on trying to detect them. Is that effort proportional to the problem?
