The Scala community soap-opera was a total shit show. Both of the women involved later ended up in relationships with Travis Brown, another prominent and extremely controversial Scala figure. Travis then entered a long running war against John De Goes and a bunch of other people in the Scala community before rage-quitting.

I don't believe the women entirely made it up, or that Jon Pretty is entirely guilt-free. Likely he is a narcissist who took advantage of his status to pursue sexual relationships where there was a huge imbalance of power. Maybe this strayed into manipulative gaslighting, I don't know. But it also seems entirely plausible that the women in question desired a relationship with a powerful older man and that the relationships were essentially consensual. It's a mess of power, sex, alcohol, a lack of shared social norms, and overlapping social and professional relationships. Quite where the truth lies between "totally non-consensual gaslighting" and "consensual relationship with large imbalance of power" I don't claim to know.

No one said it was all lies actually. Even the guy. He could say "I didn't sleep wih a young attendee of a conference I helped her get into, after getting her drunk at my airbnb". But he just vaguely said "fake evidence" and "short relationship". If what she said is true, "short relationship" is hella euphemism
