I dont know if anyone else gets annoyed by that girl, but here is how to hide her, at least temporary until page is refreshed. Using Chrome or Firefox:
Do this when she is on screen (or not, if you know what you doing)
Right Click, Inspect, Select an Element on page to inspect (box with pointer in it), click on her (it will scroll you to her div class="electra" ), couple lines above is div id="message_all", right click on it, Hide element.
Now she will be gone till next time you reload page.
