I want to know if is it possible limit the number of posts per user, and per category. In my old aplication, the users abuses of freedom. They created repeated ads in hopes of appearing more.
Of course, after I just creating a way to eliminate duplicate entries. Not allowing, for example, repeat e-mail or phone between ads. Works!
I think combining fields that must be unique to the limitation of ads per user and category will save a lot of work of the owners.
