Exclude the user from the list of fields,
ReplyFormSet = modelformset_factory(model=Reply, fields=('question', 'answer'), extra=length_questions, can_delete=True)
then set it when you are saving the formset.
if request.method == 'POST':
formset = ReplyFormSet(request.POST, queryset=Reply.objects.none())
if formset.is_valid():
new_instances = formset.save(commit=False)
for new_instance in new_instances:
new_instance.user = logged_user
new_instance.save()
