My bad.

That's a weird way to burn sats. Send a 1-sat transaction to a bunch of addresses. You would have to make a no-fee tx to move it. Then there's a 0.001BTC to an exchange maybe? That's a huge throughput of 134,856.76153700 BTC during it's course.

Are all those thousands of addresses dead ends for those 1-sat txs?

How the fk do you send to 3000 different addresses at once

Proof of concept, you can destroy Bitcoin by doing legit transactions. Those funds are irrecoverable unless there is a change in the Bitcoin protocol that allows to send 1 sat with no fee. Perhaps in 100 years we discover a way, when 1 sat = $1000.
