vBulletin linkbacks - disable linkbacks from homepage

[wheres me jumpa]

I'm getting a lot of link backs everyday....from my home page. I cant seem to find a way to disable link backs arriving from the homepage. I had a link back plug-in on previous version of vBulletin and it allowed me to disable link backs from a particular url.

But now this feature has been incorporated into 3.7, there seems to be little or now configuration allowed of this feature.

Anyone know if there is a way to configure this or even a work around?

If you're using vbseo you can disable linkbacks from a particular domain via the control panel
