I think this is your first post that you are doing from your same account that you want to delete the same account but I want to ask the question because it is your first post that you have created an account. You posted this to delete an account means you created an account to delete an account and posted how do I delete it is It's surprising that I didn't see any other post like this from you, but it's your own choice, why you created your account and then why are you deleting it, it's your own opinion.

But I don't think you will get any option in Bitcoin talk like you can delete your account as it is, but you can do it if you have sent this message to delete or you can ignore this account and create other if you need it in future.
