I was there for the original thread making the connection so I got a very fresh look at the profile. The user was consistently referring to being in dental school. A lot of posting, and not in ways that would influence opinions. Maybe a cover for more secretive mod actions, but it'd be a wastefully excessive cover.
Other mods knew them personally and were still in contact. The user claims they heard of the rumor and decided not to reactivate for the lulz.
I am not familiar with the mod side of reddit - couldn't fellow mods audit her mod action logs to find more juicy details we would have heard about by now?
If Maxwell is indeed a spy and doing what she is claimed to do, it is highly unlikely that she'd put her last name and a reference to her specific family's property in her username. This would be a glaringly arrogant choice for someone who had been groomed from an early age for spycraft, and who had any degree of oversight.
If she were part of a spy network, they would be highly remiss not to commandeer the account at the time of her arrest to avoid suspicion unless they were completely incompetent.
I am mostly familiar with cold war espionage so it just doesn't sound like the general MO to me. Unless Opsec or whatever has badly decayed since then. That's not impossible.
The mentions of the account in the files are from anonymous tips, some of which are highly absurd. They vetted a lot of tips, and I saw no information in the new releases indicating they thought it held water. We've seen the subpoena and IP tracking for the Epstein prison guard whistleblower, but no such thing on this topic.
