RoboDebt is very significant, it put paid to the "fraud" issue, the govt had to repay billions to those who were accused of debt, which was fraud by government against vulnerable humans
The Australian government has repaid over $751 million in unlawfully claimed debts and $112 million in compensation to approximately 400,000 people impacted by the Robodebt scheme. This brings the total settlement value to $1.2 billion, including debt waivers. The Robodebt scheme, which used income averaging to raise debts, was ruled unlawful by the Federal Court in 2019.
These were people "accused" of fraud, so your hypothesis seems disingenuous to say the least
