Blockchain investigator ZachXBT has accused the IRS Criminal Investigation (CI) Unit of harassing him by persistently seeking his assistance in blockchain investigations. ZachXBT detailed concerns of the IRS-CI agents resorting to various tactics, such as visiting old addresses, contacting personal emails with private data, and sending mail despite the availability of public contact methods. The tension escalated when ZachXBT refused to assist holders of the now-defunct Complex (SIMPLE) memecoin, emphasizing his willingness to support genuine victims of scams but questioning why he should assist individuals who invest in speculative meme coins.

The allegations against ZachXBT have brought to light the intricacies and ethical considerations surrounding law enforcement's collaboration with independent investigators in the field of blockchain forensics. It underscores the importance of transparent and respectful cooperation between all parties involved, amidst the IRS's crackdown on crypto-related crimes through partnerships with key players in blockchain tracing. Such collaborations have led to the seizure of cryptocurrency assets worth $10 billion as the IRS intensifies efforts in investigating digital asset crimes.
