In first page now also an .XXX domain name which is based on chaturbate feeds:
http://www.freelivesexchat.xxx
More in first page of most keywords are based on chaturbate:
http://www.livefreecamx.com ,
http://www.gratisonlinesex.com and the previously mentioned
http://www.cam7.com
Google results change often (a month ago there was lots of bonga whitelabels in first page, now no one anymore), but currently doing chaturbate based sites like the ones above it is not considered "thin content" but instead unique and very useful, I guess, or it would not be in first page.
