Terms of Service Violation Notice for Username

Just wanted to share this with the community, I had the same username for over 2 years . I recently got a violation notice and Niantic changed my username, which was “EvilNintendo” I don’t know why this name was flagged as offensive. When I asked questions they hardly answered them and in the end shrugged me off. Below is the last screen shot of my ticket(since I can only load one), would of liked to share full interaction. In the end they force closed my ticket and never answered all my questions. Why are company’s allowed to get away with this, I just want the community to be aware and be careful.
