No, hacks that people use are allowed on the server. Unless it harms the server, like you said, the player will be banned.
Hacks are allowed unless they harm the server. In this case, they don't actually harm the server much, but they do crash players, and anyone caught doing it will be banned.
Hacks that harm the server OR its players will result in a ban. This is harming the players so they will be banned.
You've probably accepted some sort of tpaall and picked up one of these items that the hackers drop that makes you crash, if so, you may need to be reset or something, otherwise you will spawn with it each time and crash each time.
