I don't think she's cheating at all.
I didn't watch the demo but I already know who the person is, and nothing really shocked me when I played against her.
Also when you post a demo, precise at which moment you find something suspicious, so which round with eventually the approximate moment(you can see by pressing SHIFT+F2, it will open the menu to fast forward, go back, etc. and you have the tick or time.
It would help anyone who want to watch the demo

I think most people know bunny for quite a while here. It doesn't necessarily mean that we can rule out any suspicion, but if you have some round or specific time on the demo you think are odd, I'll watch it and give you my opinion.
