It is in conjunction with a route server. The filtering I meant would be that network A wants the IX to drop all advertisements to them from network B. Normally solved by network B putting a community on their routes to not advertise to network A, but network B doesn't want to do one-off configs.

Unless this is in conjunction with a multilateral peering session (“route-server”), when prefix-filtering is something that the IXP very much should be doing.
