Her husband was fined for running a ponzi scheme and several people who mentioned it got shadowbanned.

Plus she intentionally got herself fired from the job she had before reddit and then sued for sexual discrimination. (She lost that lawsuit and had to pay quite a bit for the company's legal fees iirc.)

Add a bunch of tension because of gamergate supporters and a few other groups getting shadowbanned, and then add the FPH ban, and that's a lot of anger.
