Hi everyone,
\nI don't want to blame anyone without concrete evidence but this team and members of it seem a bit unusual/suspicious to me. The first 3 accounts opened exactly 9 years ago (please check out the naming similarities as well) and the last account is just 6 days ago.
\n@auaacmee @buaacmee @duaaabcd @wisewhoyh @zbb1997
\nAs of now, they are in 37th place on the leaderboard with a team name: ZBB||YH
\nI am wondering your thoughtsβ¦
