Hi, I think that automatic deletion is not the best idea. Some ads may not be limited in time. I think that the old ads can remain. On the other hand, I thought as it had been suggested, a system of questions to the seller. As well as a notification, at regular intervals, to check if his ad is still active, because in v4, each user will have a notification system like Facebook. This will be more practical to draw the attention of a member on a search for unsolved scores, an old ad etc.. we can even imagine notifications generated by me or cindou for a deposit not compliant, a reminder of the rules, a penalty of any kind. In short, all this in order to lighten and automate the work of the administrator, without penalizing the members
