I've seen many free sites that have an exit link to a non-adult site, such as Yahoo or Google, and I've seen many that do not have an exit link, only an enter link to the site. I haven't found any LL's that require an exit link, only that it point to a non-adult site if there is one in place. Why have an exit link? Is it better to have one? If so, why? If someone doesn't want to continue there's a little red "x" in the upper right corner that will do the trick and there is always that left facing arrow....
Not a big issue, I was just curious how others felt about it.
