I can't make AdSense revenues from a Twitter account.

In fact, if Twitter or Facebook suspect I'm a professional concern rather than simply an ordinary Joe, they may expect me to pay them money to promote my content, or even to make it visible.

I already have dealt with exactly that on my 'regular Joe' FB account in the past, because I had pages for my book label attached. Thankfully they seem to have realized that there was zero traffic to them and stopped, but I still sometimes worry about how much of my stuff is actually being 'curated' out of my friends' feeds.
