When I first started FR I used to blast Dem Senators with letters at least once a week...
...until I was audited by the IRS.
I remember at the time I was only making 50K a year.
Imagine that.
Disgusting, and all it took was a phone call.
The audit might be done by IRS, or the audit could happen as part of a university audit of eligibility for Pell Grant funds. Well over half of these recipients were audited every year ~ taking up more than 30% of total IRS audit resources.
The other trillions of dollars in federal tax payments were subject to cursory evaluation.
You were just unlucky!
