I would consider using facebook if there were articles like that. Not sure why you consider this a problem... "Because I can" is a good enough reason to do anything that doesn't cause harm to others.
Might be because of my ignorance of other areas of human activity, though...
It's hard to tell in advance how any action may impact others. The extreme example: jumping off a bridge doesn't physically harm others. But having to look at, examine, or otherwise interact with your corpse may inflict trauma on others.
