Player name: MassiveBird132
BF4DB: https://bf4db.com/player/1782212823
Played a round against him, felt something was off. Looked him up here and besides some elevated KPM he seemed normal. However on the front page under "Latest bans" we have a player named MassiveBird123 ( https://bf4db.com/player/1066194596 ), who is very much a cheater and was banned recently.
MassiveBird132( not banned) plays together with clan members from MassiveBird123(banned), so I suspect that it's the same player on a different account.
None of the battlereports stand out as suspicious, so there's no real hard evidence that this account is cheating, but I think there are too many similarities for it to be a coincidence. If it's the same person he appears to have learned to dial back his hacking to subtle levels because all I could really see was some ESP use.
