The community, r/Efilism, is devoted to a philosophy mentioned on a website published before Saturday's bomb blast.

Bartkus is believed to be the person who detonated a bomb at the Palm Springs American Reproductive Center, which offers services like IVF, because he was aligned with the pro-mortalist and anti-natalist movements—the idea that humans should not continue to procreate.

Reddit banned an anti-natalist forum for violating self-harm rules in the wake of the Palm Springs fertility clinic bombing.
