Limit Number of Ads Based on Time
I would like to be able to limit the number of ads that can be submitted by a user based on a specific time frame. For example, place a limit of 1 ad every 5 days or 2 ads per week. I am already limiting the number of ads a user can have online at a time, but they can still delete an ad and create a new one to get around that. I need a way to prevent users from creating more than X number of ads per X units of time. It would be best if this were user configurable. Thanks.
