Network Sites usually give their members access to numerous websites in different niches, for a very low price. The main advantage of these sites is that including so many sites in the deal, and usually updating each one of them at least once a week, they give the member several global updates a day. The disadvantage in some cases is that based on the total number of updates to the network, some porn producers slack off and stop updating as often as they should, so granted, you end up with two or three network updates a day, but may be for that specific website which is the one that sends your cock soaring, there is only new content added once a month.
