I think this article explained well that she in fact wasn't tweeting about Elonjet but about the time he doxxed an ex-employeur.

I remember it was before the idiotic pedophilia accusations, he retweeted someone who doxxed her email address after tweeting about her like 5 times in a row, i thought 'wow, not cool'.

Here what I found [0]: "This is worse than just stalking: Musk is setting his army of fanboys loose on Lopez, he’s retweeting stuff they find, and he’s encouraging them every step of the way. Milo Yiannopoulos was banned from Twitter for setting mobs upon his enemies; Musk should be banned too, but won’t be."
