no u dont understand^^
sm_resetmyrank is not activated or if it is its in admin_overrides
some guys are using some steam auth exploits so they dont have a steamid and so the ranking gets fucked for them and they can reset their rank etc.. see links above
edit:
it will show STEAM_ID_STOP_IGNORING_RETVALS as SteamID in database and onother new entry then with real steamid and new rank..but even the old rank with STEAM_ID_STOP_IGNORING_RETVALS is broke and not the amount of points and kills the guy had before
i mean no big of a deal i just ban these guys anyway but just wanted to let you know if u not already aware of
