Ehh, I was a moderator luckily only for a few months with the whitelist system, and it was not fun. I remember going through newbie jail, I dont think it had a post requirement at the time, I just left Bitcointalk open for 4 hours and just went and did something else. I also delayed signing up for a few months, using a friends account because I didn't feel like going through newbie jail. People don't seem to realize that getting rid of newbie jail doesn't really change much, it just delays spammers/bots by 4 hours, so essentially after 4 hours of changing the newbie jail system, things would go back to normal. Anyway, report bots/spammers/account farmers if you see them. There are a few staff members who are really good at purging large numbers of spammers at once. Report one, and 20 will go away quickly.
