I was solving atcoder problems and found 2 profiles with similar names https://atcoder.jp/users/purslane and https://atcoder.jp/users/purslane_ma. They refer to cf profiles: _Purslane_ and ttmasoi. Both profiles have the same organization name "Maanshan No.2 High School". I found 4 more accounts with that organization name: M2GA, Stannum5307, TrueCX, False.cx. All 6 accounts have the same templates and code style. Is this a new way to promote high school? All 6 accounts should be banned for violating cf's terms.
