English Translation
How can I deactivate my account on this site?
doesn’t usunąć mean delete? deactivate is more dezaktywować right?
You’re absolutely right, this translation is wrong. It also doesn’t clearly imply that it’s “my” account:
Jak mogę usunąć konto na tej stronie? / How can I delete an account on this site?
Jak mogę zdezaktywować moje konto na tej stronie? / How can I deactivate my account on this site?
