It is never too late to earn some money, my friend 🙂
I have never used the script called “Roboscripts” but I would not recommend to use it because it will be really hard to get any organic traffic to the adult sites that are using such a script because whitelabels and scripts that run on auto-pilot, are going to get penalized by the Google due to the duplicate content sooner or later.
You need a great site with a quality, fresh content so that is why I would suggest you to start a blog around cams or preferably an adult tube site. It would be better to start a micro niche site, for example: a bbw cam site, a gay cam site, a straight black cam website and et cetera. Why? Because it is actually easier to rank such sites because there is a way less competition.
