The dangers of monetizing a Twitter feed

I’ve seen commentary about how this article on the successful monetization of photostream Twitter accounts by a company called Kulfoto ignores that the copyright situation of the photos it shares seems to be … unclear at best  However, I was struck by something different: the apparent noncompliance with the FTC’s guides for presenting sponsored advertising  The ad for Chegg that appeared on @CollegeStudent contained no disclosure that it was an ad  Even if copyright owners don’t come knocking, the FTC might—and the FTC will have questions both for Kulfoto and for the advertisers who paid for these spots.
