10HP useless on normie?

I saw this guy training range with a cannon, "One Hit Dead", whose 10hp 1 Defence, but not an ironman.

Seems kind of pointless no? Because as soon as they rush anyone they will get hitpoints experience.

Unless the plan is to never PK - it's strange to call yourself One Hit Dead and it seems pointless to make a non-ironman 10HP account.

Is there something I'm missing? A 10HP normie seems more like a trophy than having any practical value.
