I think part of the reason this gets so easily dismissed is that people still see reddit as a quaint little internet message board rather than an influential mainstream juggernaut that reaches half a billion people every month.

That account is/was enormously powerful, with the ability to determine which stories reached the frontpage and which didn't. That makes it politically and financially very valuable, and I don't think someone would just give up that because of association with Maxwell when they could have just posted a single comment saying "I am not Ghislaine Maxwell" and everyone would have forgotten about it.
