That cam script seems pretty decent but personally I haven't figured out how to market a cam site. Seems like a catch 22 to me where broadcasters won't waste their time without customers, and customers won't come without broadcasters.
I've always run the porn sites on a cash basis, I started ten years ago was just out of high school, at that point it was literally a blogger.com site with non-nude photos and a search engine box. I made $22 the first day that site was up (adsense paid real well back then), did about a grand a month from that for a few months but with a lot of repeat traffic the revenue started to drop pretty drastically. I let the site rot away at some point, domain expired years ago. Realistically I didn't see a blogger.com site with non-nude photos to be that great of a business plan; depending on adsense didn't seem like the best idea and I already knew other places weren't paying as much.
After that I dabbled in mirroring downloads, I took torrents from akiba-online's message board, download them, re upload to places like depfile, and then just post the links in their download sections as a mirror. This can still be done today, the same message board still exists, costs nothing to start except for having a very fast internet connection.
At that point I did drop shipping of sex toys for a while, along with producing porn. Made a couple videos, never made money off the videos and basically figured "no one's paying for porn, so I'll setup free sharing sites."
Then I had a few file sharing websites, just for files, before going to tube sites. Tube sites took A LOT of learning, which is why I've gone through script after script. I already grew up quite geeky working with Linux and such but getting everything to work properly was quite the challenge.
Last year I profited just over 20k but it's really a side gig for me. I have a regular job in tv, which is how things like drop shipping worked for me but I dumped as dealing with customer support didn't work very well when I had to travel around for work. So yeah, it's really just stuff to make sure I'm not bored.
The thing that people IMO get stuck on is it takes money to make money. The difference between spending money and not spending money is the difference between being able to scale; starting a business with no money is possible but in the case of porn you'll be uploading and doing everything yourself. If you spend a grand, now you can have user sharing, and it becomes automated. Once it's automated, then it becomes a trivial process to purchase a handful of niche domains, and sit back while your users do their thing.
... so here I am trying my 3rd site.
