Question: I think my stats might have been altered by a hacker. Is there anything I can do?
Answer: When playing Call of Duty: Black Ops 4 online, it is highly recommended that you play in Public Matches, or that you only play with players you know and trust when playing in Private Matches. Accepting Private Match invitations from players you don't know and trust might place you in a hacked lobby, which can leave you vulnerable to having your stats artificially padded, or boosted.
Please note: Having your stats knowingly or unknowingly boosted by a hacker might lead to your stats being damaged beyond restoration, and might also be grounds for a ban.
