If those fat fucking pieces of shit bothered to read the Terms of Service for Facebook, they'd have noticed this:  “transferable, sub-licensable, royalty-free, worldwide license.”  This means that Facebook can license your content to others for free without obtaining any other approval from you. Similar terms exist for most other social media services, too. So, yes, technically you may still have the copyright, but you agreed to license all your photos, etc. to Facebook, so you're shit outta luck, you motherfucking hams!
