I think it could be a fair point “it doesn’t allow for any progress in human beings” however I’d argue that context is relevant. She traded on being “pretty honest” and talks about people describing her as lovely.
That jars when she is not entirely honest and behaves badly - stalking people on socials, making threats to contact employers etc - don’t forget the local man working for the wine merchant was only in the last year or so, not to mention tracking down people here and sending them emails telling them they’re mental. Things from her past get dragged up because it seems more like a pattern of behaviour from Sali, than a one-off.
She may not be a core Guardian writer, attending meetings with the editor and sitting in the Central London office however to the average person she has clout, she has standing, there’s a power imbalance when she threatens you, your employment, your privacy. Whether she acknowledges it or not.

Also of note she “interviewed” Kate Hayes, legendary MUA who was also being relentlessly trolled. An insider on those threads said that Kate and her management were hyping/sending the troll messages for engagement. Kate also lost a contract when her old racist and homophobic tweets from 2012 we uncovered.
