I don’t think many of them are still active in the fandom spaces the way they were during the late Jordan / early Sanderson years, unfortunately. Terez pops up occasionally through old Reddit posts or archived theory discussions, but she seems to have stepped away from regular forum activity quite a while ago. Luckers more or less disappeared from Dragonmount after his old farewell post about real-life commitments, and I haven’t personally seen much from Suttree or Mr Ares/Ayers in recent years either. ()
Honestly, that whole era of WoT theorizing felt very unique. Dragonmount, Theoryland, WoTmania, and the old forums had a core group of insanely dedicated posters who practically treated the books like academic texts. Even when people disagreed with them (sometimes fiercely), posters like Luckers, Terez, and Suttree really helped shape the culture of theory discussion back then. A lot of those conversations are still fun to reread today.
My guess is most of them simply moved on with life once the series ended and the daily theorycrafting disappeared. The fandom itself also shifted heavily toward Reddit, Discord, YouTube, and social media over the years, so the old longform forum style mostly faded away. Still miss those days a bit, honestly.
