I'd go with ever green niches people will always be active in, regardless of spam. You can go the direct route of clone spamming, which will result in a ban or loss of income really fast, or you can go with a slow growth into a very big niche celebrity. My niche is movies and another is games, no secret there. I target people with my own self created content, not walkthrus everybody seems to spam. For me I got forums where I can post videos or images of self created content to drive visitors, namely places like Reddit, *****, Newgrounds. These people don't like spam, but if you are a content developer, then you'll fit right in. This is why I advocate Quality Content that people make, not reposted pics of some butt 3 billion people saw before on thousands of different accounts. Ifyou are gonna go fitness girl niche, at least invest some money into hiring models to go play in the sand or water, rather than scrape from Google and expect converting CPA products. Just no, because it is spammed to death, and when quality does come along it booms into a new solid money green account, and the spammers go broke and cry.
