Asking good questions is always welcome!
The genuine truth is no one but Liz and their victim currently know what happened afaik but:
1) Liz is EXTREMELY well known for spending every waking second of every day trying to cancel, dox, and otherwise ruin the lives of people who cross them. This is a pretty easy explanation on why the victim hasn't spoken out (I haven't been part of LFJ lore for about a year so I assume this is still true)
2) Is extremely defensive about this to the point of insanity, which leads most people who learn about this to believe the most Occam's razor explanation, that Liz did something awful to someone and has intimidated them into silence, and is taking that approach towards any other platform that can provide credible evidence of the 'consent accident' post
Honestly I think LFJ would be much happier and fulfilled in life if they stopped trying to attack people online (and now legally irl) nonstop 24/7, it's a self fulfilling cycle. But hey, old saying about lolcows not being lolcows if they were capable of learning from their actions and all.
