Before making a comment on this page: AccountKiller DOES NOT (and CANNOT and IS NOT ALLOWED to) delete accounts in your name. You should do this yourself.
Their terms state: "You may terminate your membership at any time, for any reason by following the instructions on the Resign pages in Account Settings, or upon receipt by CitySex of your written or email notice of termination."
However, 'resign' never appears on the Settings page, perhaps this only goes for paying members (which we are not, obviously ;)). So instead: (1) be logged in on the site, (2) click the link to go to the support section. (3) Scroll down for the webform, you'll see it under How can I contact customer support, then click Contact Support form. There, request deletion using the form.

Publicly visible text/images often aren't properly deleted even when you succeed in deleting an account. Try editing or deleting them manually before deleting the account itself. If you're unsure what happens to your tracks you can always contact Citysex and ask personally. By the way, deletion requests don't necessarily mean your data will actually be deleted (e.g. due to legal obligations).
Si no puede encontrar ninguna información de contacto y todavía desea hacer algo (por ejemplo, una pregunta acerca de lo que se elimina, sobre la retención de datos, etc.,), usted puede contactar a los propietarios de dominio utilizando esta información.
