Is it trackable or was it during 2018? What could Pony provide that a high-level statistician, mathematician and compuer scientist could not come up with hired by the government? I think Monero right now still is safe if you use proper OpSec.
We had a dev team we paid yearly 5 million USD .Top notch devs which are working now on top 30 projects as leader devs.
And it took them nearly 5 years to find out that a scammer dev minted an additional 250 millions of tokens and sold them over time.
So much to your question what he could provide.
If he knows what he is doing and how to hide it there is no way to find it quickly.
That scammer dev tricked everyone.Our devs,our community even the code was open source,Dan Larimer who created EOS,Exchange Audits etc......
It came out by luck when a dev was rewriting an old code and stumbled on it.
