Ok, evidence is needed when you report someone be it staff or a normal player same rules apply.
Don't say stuff you don't mean such as the 1000 dollar donation.
There is a farewell section.
And last don't double post just edit your post when you feel like adding something.
What you should do now:
Think of some ways of proving that you are right about this. ( always have a backup plan halves your chances to fail doubles your chances of a win and you could have an "epic" comeback too!
Consider taking out that 1000 dollar part.
If you really want to see her go, try to get some screenshots if you already have, kudos to you my friend just post them on here.
And if you're quiting the forum has a special board just for those topics just post it in there else your topic might be considered spam, remember that for the next forum you might decide to join or hopefully stay on this one and prove you're right like a true person would.
Never give up without a fight, preferable a verbal one.
