"FACEBOOK TERMS & CONDITIONS
We have seen a large increase in the last couple of days of people joining our Facebook page. On further investigation of their own Facebook pages it is clear that many have come from or via Mumsnet with the sole intention of continuing their theme of attacking men and Fathers 4 Justice. This will not be tolerated.
We welcome intelligent debate and argument we do not welcome attacking people because of their gender, be it men or women. Likewise as I am sure you are all aware by now we do not tolerate posts from dads attacking women/mums and we are very vigilant in removing these posts and people.
Over a third of the supporters in F4J are women because when a dad is denied contact that affects their sisters, their own mothers (the grandmothers), their new wives and girlfriends and ultimately their female children. This is why it is so sad to see and read such hatred in the posts we have seen over the last week on Mumsnet. As far as I am concerned the failure to moderate those offensive posts can be interpreted as them being the view of Mumsnet the organisation. I wrote to them last night as the posts were becoming more libelous and I am sad to say that we are taking legal advice this morning on this matter as the posts continue to come in and have become even more serious.
While we are all shaped by our own personal circumstances we hope that you come to this campaign and Facebook page able to understand, or be prepared to understand the bigger picture. No one more than me had reason to set up Mothers4Justice but I did not because the only place that offered sensible help, advice and debate about the failing court system was Fathers 4 Justice.
Be under no illusion, this Facebook page is monitored not just by those with a personal axe to grind looking for information about their ex's, it is also monitored by the Police, Cafcass, NYAS, Family Courts and Legal professionals. It does our campaign no good if you then resort to the level of these people, and the sort of people posting gender hatred on other Forums.
Our focus is on equality. We are campaigning for the right of both parents to be treated equally in the family courts. Let others go down the road of in-equality. Nadine"
