You're a private citizen (I assume?), so far easier to automate than the big guys. That was probably a result of them "being digitized" (see my other comment around here), so some buggy automatic system kept flagging you and the poor drones had to respond to the ticket.

Meanwhile, the real big tax fraudsters use convoluted bespoke schemes that the IRS's clunky systems can't be ayutomated to detect, so no tickets are raised about them.
