If you obey the rules, you will never be banned, plain and simple. By donating to WinterCrest you are not entitled to any Physical or virtual good, a donation is a donation and not a purchase.

I was kind enough to offer the rank to your brother, before he disrespected our server and had himself banned.
As a result, we will not be returning the kind donation you made. However, I would like to thank you and assure you that your donation is appreciated and has/will be used towards maintaining our server.
