Quick Rundown
Do you like tangerines? These guys do. A lot. That's because it was discovered recently they're sentient. Well, The Tangerine Cult (TTC, they included "The" because they believe 3 letter acronyms are more powerful) discovered recently people have considered tangerines sentient for millions of years. They seem to be the only ones who believe this, though.
Plenty of their members don't give a single fuck about the whole tangerine thing and just are in it for the fuck around factor. They do a lot of hacktivism (computer hacking for activist causes) which draws in randos who are good with computers. A lot of these people join for one event then leave once they see how deep the rabbit hole goes, though.
This whole hacktivism component introduces a long, painful series of wrinkles into their public image, though... Wait until you see how other ecoterrorist organizations feel about them. ;^)
(And yes, TTC is fine being called a cult, don't worry.)
