You can't.

why not?

because you will need it when you return to kdice

if you want to quit,just quit, Ryan doesn't charge you for having an account you don't use so why would you want to delete it then?

to reduce the risk of returning

that won't be enough to reduce the risk, you will return eventually

my advice: sell your PC and go live in a remote tribe in the brazillian rainforrest if you really want to reduce the risk with a few %.

nah, i seriously think about showing racist and sexist behaviour in order to get my account banned.
would that work?

i guess so , but you might be able to get fiero or grunvagr to block your account if you find them and ask to be blocked.

... is there a way to delete someone elses account?

Might be a good option sometimes.
