Andrea did nothing wrong (change my mind)

A popular narrative surfacing is how Andrea has spoken poorly about other cast members and how she’s malicious. I have yet to see any videos or posts where she has done the things she has been accused of; most of it is just moments where I suppose you could take her words the wrong way. The way people ganged up on her at the reunion when she was trying to make things right was absolutely disgusting to me, and I personally don’t think she’s done anything wrong or at least enough wrong to warrant a response as heavy handed as that. Am I missing something? What’s the big bad that Andrea has done?
