As the Django documentation on related_name says:

If you’d prefer Django not to create a backwards relation, set related_name to '+' or end it with '+'.

If you thus have two models A and B, then by setting a ForeignKey from A to B, Django will add a manager to B to obtain all related As for a given B, but by setting it to '+', we disable that behavior.
