I do all 3 when I record a demo of a hacker...and right after I email it to the anti-cheat team I log in to SteamBans and submit it there too
not that I dislike hackers and want to see them banned from as many servers worldwide as possible or anything....or wish there was a cexec command I could run on thier computers that would cause them to reboot and run DBAN in the middle of the night...
