Networking systems and methods according to exemplary embodiments of the present invention can provide robust filtering to enable users to customize their networking environments. A networking system can comprise a plurality of interfaces, a request unit, a management unit, and a filter unit. Each interface can include a plurality of displayable objects, each of which can represent some user of the networking system. The request unit can receive from a client a request for one of the interfaces. The management unit can manage filters, where each active filter hides one or more users from one or more other users. When an interface is requested by a client associated with a first user, the filter unit can apply the active filters to the requested interface to exclude displayable objects that represent users hidden from the first user by one or more active filters.
