How to Deactivate a Craigslist Account
Craiglist is a classified ads website that allows you to post free or lost-cost ads for everything from pets to jobs. Craigslist gives you the option to create an account to easily manage your posts. It's impossible to delete an account after it's created, but there are ways around this problem.
Do nothing. Craigslist automatically deactivates accounts that have not been accessed in several months.
Send an email to firstname.lastname@example.org and ask to have your account deleted. Be sure to include the email address on the account. A human reviews this account and will respond to your request.
Change your Craigslist email address to a throwaway email address that you don't check. To change, log in to your Craigslist account and go to My Account in the upper right corner.
Choose Settings and Change next to the email address associated with your account. From there, you can add a new email address and save it to your account.
Check your email at the newly entered address and follow the direction to confirm the change.
