How should I allow my members to cancel their accounts for my site?

What is the best way to allow a member to cancel their account? Should I simply have them click a cance开发者_高级运维l button on the site?

Have a button or something that allows canceling the account with confirmation so that the user doesn't cancel by mistake. Also don't delete the account, have deleted flag in the users table so you can reactivate that account if needed.
