If set, the cron job will remove the ads only after expiry and not when sold.

A plugin can be used for this purpose.
Is there an option in the profile page to add an avatar by the user?
Email is sent once the ad has expired.
Do users get an email before their post expires as a notification?
The reCaptcha can be enabled in the registration to deter automated bots registrants/spammers.
Is classipress a target for spammers? How is it protected from spam?
