You've crushed the dreams of a lot of people who get their tax tips from anonymous internet posters.

"Deposit $9,999 to fool the IRS" is up there with "Consult with top divorce lawyers to keep them from representing you spouse" in the Hall of Bad Legal Advice.

Yeah...there's not a COBOL program running someplace saying IF DEPOSIT IS EQUAL TO 9999.00 THEN FLAG-IT. There's some pretty sophisticated machine learning work being done here, and all the major banks these days have a data science team working the problem.

Sadly there probably is such a COBOL program but it's only going to be the first in line of a lot of systems looking for fraud.

Why is that sad? Since there are a vast collection of morons who see "transactions over 10k will get flagged" and 'cleverly' say "ah-ha! I shall beat the system with 9999.00!", why wouldn't you want to spot that early and easy?
