yup, every demo I record I use the sb_status command so that I can send it to Steam Bans as well as the Spawnpoint Anti-Cheat Team. Our guys have the demos reviewed within a couple of days and add the IDs to our global ban list so we don't have to deal with them again...Steam Bans takes weeks (sometimes months) to review the demos, but once they do that makes for another several thousand servers the hacker won't be able to play on
when I submit to steambans I also include a copy of the map file if it is a non-standard map, since I had one last year where when they finally tried to review the demo it turned out to be a custom map none of them had. I had to go digging through all the custom maps I had downloaded to find it and email it to them.
