That would not necessarily be sent to the IRS. In which case if I were them and someone truly sent me thousands of pages of transactions that showed basically no gains I'd troll them right back and flag them for an audit. Then they could spend the next month of their life reviewing every single transaction they submitted with one of the IRS's many thousands of taxpayer funded employees. Never mess with people who have the legal authority to make you life a mess and have zero accountability for it.
