slacktivist

Originally it referred to a political activist, whose idea of political activism devolved into just forwarding e-mail protests to other slackers. However, this term has morphed to mean anyone who uses digital tools to support an organization or cause in a surface, quick-and-easy way, like texting a $5 donation to Haiti relief efforts, or signing an online petition, without really becoming deeply involved with the organization or cause.

Historical perspective: The ice bucket challenge in 2014 was initially thought to be a fad or effort-free "slacktivism" but it ended up raising $220 million to fight the neurodegenerative disease ALS and by 2016, that money was the catalyst in two groundbreaking discoveries. Score two for slacktivism.
