Slacktivism
Slacktivism (a blend of slacker and activism) is the practice of supporting a political or social cause by means such as social media or online petitions, characterized as involving very little effort or commitment. Additional forms of slacktivism include engaging in online activities such as liking, sharing or tweeting about a cause on social media, signing an Internet petition, copying and pasting a status or message in support of the cause, sharing specific hashtags associated with the cause, or altering one's profile photo or avatar on social network services to indicate solidarity.
