I don't wanna link to reddit so I'll try to summarize. Suspicions that maxwelhill was maybe-possibly-probably-perhaps ghislaine maxwell's reddit account, and said account had the most karma of any reddit user, was a power mod on a lot on influential subs and posted prolifically...things that you'd say were of a "propaganda" nature. Nothing was proven but gaps in the user's timeline (there were very few) matched up with things going on in ghislaine maxwell's life...like getting arrested. No new posts on that account since she'd been arrested.
The whole things very...weird.
