You brought in the term 'malicious'. I mean not 'malicious' (I checked the exact meaning now) but 'harmful'. There is quite some difference between these terms. 'Malicious' means to have a bad intention. 'Harmful' can cause damage without having a bad intention.
You are convinced after doing close to no research by the looks of it, since you had missed my comments on her 2nd and 3rd last comment.
That is not true, as these comments came after I had written my comment. That means at the time of my comment I had no chance to find them anyway.
Concerning the downvotes on her main posts I still didn't find any explanation (maybe I have missed one?). But true, I only went a few months back as my time is limited.
