I'm going to copy/paste acroman08's answer because there is no button for deleting your account but there are some workarounds for that.
apart from what NotFuzzyWarm said, if you want your account not to be accessed by anyone(including you) you can lock it by going through the "forget password" and using the "secret question" to change the password, if you use it your account will be locked.
if you don't know how to do it, here's a step-by-step guide from a forum staff on how to do it

Everything's working fine. Here's a step-by-step guide on how to do it, from start to finish.
Go to your profile, click on "Account Related Settings" and there you will find the item "Secret Question". Next, enter your question (1), the answer (2), your current password (3) and click "Change profile". That's it, the secret question is set.
Then you log out of your profile and are going to log into the forum again. On the forum login page, click the "Forgot your password?". On the "Password reminder" page, enter your username and check the "Ask me my question" box and click the "Send" button.
Next, here you enter the correct answer to the secret question you set (1), a new password (2) and again a new password for confirmation (3) and click the "Save" button. Yes, you can enter whatever password you want. You won't need it anymore anyway.
Congratulations, you have banned yourself
