Intent:

It is common for Facebook users to alter their profile pictures in support of some social movement they and their friends consider important. The most recent example of this phenomenon is the sudden flood of rainbow profile pictures in response to the Supreme Court ruling that legalized same-sex marriage. Others include green tinted profile pictures in support of the Arab Spring, or equal signs as profile pictures, also in support of same-sex marriage.

Then there's the Kony 2012 campaign. Spawned from short film intended to bring attention to African militia leader Joseph Kony, it was an effort to have the war criminal arrested by the end of that year, though it eventually died down amidst corruption accusations and the film's director's public mental breakdown. The campaign has since ascended to almost Internet meme-levels of notoriety, often ironically cited to call attention to "slacktivism". 

What if I changed my profile picture (and possibly cover photo) to one supporting the Kony 2012 campaign? How will people react to the reappearance of such a forgotten event? Having never participated in any of these profile picture movements, will this change be seen as genuine, ironic, or sarcastic support, or some combination of the three?
