Here's a long, detailed post I wrote about it but the gist is that Jill used to go by the content creator name Sursum Ursa on TGWTG/CA and wrote a blog about why trannies shouldn't beat up old British ladies, which pissed off Lindsay and her clique so they unpersoned her. Much later, Jill happened to join Nebula and did a video with Tom Scott about stage fighting which once again pissed off Lindsay and caused her to tantrum to Nebula mgmt. As Tom Scott had millions of followers, this did not go well and within 24h, Lindsay announced her departure from the Internet. Jill left Nebula and found significant success with her excellent
Fantasy Heroine shorts series and subsequent book (which sold over 25k copies upon release despite being self-published with no advertising and made a profit, unlike Lindsay's literary abortions). In short, Lindsay is a petty, bitter sow and Jill has never discussed any of the drama publicly for clicks.
