Of course this works and will until social medias stop accepting rssfeeds and auto feeders.
I got a box that is dedicated to porn only and i do something similar
Don't use free proxies to create your social accounts by the way. Do like he said and create legit ones in MDCDO/TIM HORTONS etc...(if you don't have private proxies that is) it takes time to setup everything but after that, it's on auto pilot and it keeps growing and growing. The worst that could happen is, you will have to get a bigger hosting account LOL but then again, the money will have start pooring in.
Here's my little secret.
Start building your own brand along with using the sponsors he talked about.
Ex: a whitelabel site dating and/or cam This will benefit you in the long run. You could flip it after a few months if you like or keep it growing
