There will always be a new hack out now and then, but not for long, we allways get them who use the, its all about some time before they always come to out forums or IRC to cry their innocents.
There will always be undetected hack out there ramping servers, because server admins lack the knowledge how to protect their servers.
AC ( Anti Cheat) is all about reaction, we need to know the cheat before we can detected, but game servers is not updated or do not stream to AC sites like PBBans.
If that server you was playing on had been streaming to us and the fact the game would have an demo recording feature you could made a demo recordings, hand that demo recording over to the server admins and they could submit that under their streaming account.
Actually it is not that many hack out there as many think, but allot more unprotected PB servers.
With the service of reviewing and banning demos here at PBBans I think the SGAs is very great full for this and actually do an difference in making PBBans streaming game servers clean for cheaters.
