The same people are still here, every day, doing the same things: teamkilling, glitching, being racist, homophobic. Giving them 15 minutes bans won't change anything; I know you are desperately looking for players, but letting trolls keep ruining matches will only kill the game even more. Teamkillers should be banned for a month after 3 bans, but no, after the 15th time they are still teamkilling at spawn wasting everyone's time. If you can't keep up with the reports, just release private servers and let private admins do the job.
