Specifically, it started out to track, dox, and harass Chris-Chan (originally just for being a weirdo though they eventually came out as trans and made news in 2021 for being arrested for incest). The nearly two decade old (since 2007) ongoing campaign against them means they are probably the single most documented human being in history.

They don't often target women just for being women, but much like with trans people and furries they also hate a hate-on for crowdfunded youtube personalities and fat acceptance and all of those groups do have their share of women (especially the last one - fat acceptance is primarily about women). They even target fundamentalist Christians and Quiverfull families sometimes (which tend to be very Conservative).

Also, there's no "was" - they still exist are are operating.
