Why would it be? You’re just mining like any other person, except you’re doing it faster than anyone else. I think the poster has mentioned that this is purely for educational purposes; they’re not trying to steal everyone else’s money.

On the contrary, you're contributing to the success of the coin by dedicating your personal resources to increase the total hash rate. It's not a denial of service, it's explicitly providing the mining service that the coin is asking it's participants to provide.

Now using that temporary hash rate imbalance to issue an explicit double spend attack could be considered fraud. But that's a totally separate.

Try calling the cops about a 51% attack on your Einsteinium and see what happens lol.
