In short: আপনি can't মোছা your own profile. Proceed as আপনি would with a spot. Flag the account and give a reason as to WHY it should be deleted.
Do not randomly মোছা your পরিলেখ because আপনি thought of a funnier username, want to change something etc. If আপনি have a serious problem (like আপনি feel your account had been hacked,someone stalking you) contact the F4!
