Welcome to the club. I inadvertently traveled with not one, but two large box cutters in my carryon satchel for at least 20 flights before I discovered them while searching for some swag. I put them in there for a booth setup in Vegas years prior. Sent a completely calm, even sympathetic report to the powers that be, got put on the DNF list for my troubles.
Still screened and detained 100 percent of the time, sometimes for hours, sometimes having to surrender personal devices, decades later.
The message is very clear.
You sent a report saying you were not searched for 20 times and now you are searched all the time? Has it been over 20 times that you have been searched?

What were you hoping to achieve by sending that report?
Most people would have just thought "wow, lucky I wasn't caught with that", taken it out of the bag so it didn't happen again and carried on with their lives.
Deviating from that normal response makes it look like you're just trying to cause trouble.
