At Ask.com, we believe questions and answers are forever! Questions, answers and comments you make on Ask cannot be self deleted. The only items which are removed are items that violate our Community Guidelines - otherwise, they are here to stay. This benefits not only those people who are reading along right now, but in the future when others search the web for the same information, your contributions today remain in place as a resource for them as well. Therefore, this is a good reminder to always be careful about what you say online, because what you say on the internet, stays on the internet.
If you have a specific need for removal of a question or answer, though, you can contact our Customer Support team for further assistance.
