It won't be an actual time limit that stops you from leaving fb, it'll just be so that if the same person leaves you two fb in x amount of time, one of them will be removed. If that's true, why even have fb? Just have a thread stating how much you've traded and stuff. Limiting it to 50 fb would be completely pointless. Everyone knows quality > quantity, but quantity also relates to experience and determination since you're doing it over and over instead of just a few times and then stopping.
