True indeed,the newbie jail thing can be imposed again but with better restrictions which deride the disadvantages away and concentrate more on the advantages.
I do not get why de newbie jail got removed anyway? It was a good concept to keep the shit out of the main board, and prevented peopple from making a shitload of alt accounts.
Probably because it's easy to bypass and just hinders the legitimate people who are registering on the forum. I'm going to quote Saltyspitoon's comment on the newbie jail.
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.
He experienced first hand what is was like to be someone who was forced to go through newbie jail, and someone who dealt with the newbie jail as a moderator. Maybe, like Radioactivetechguy suggests it could be beneficial to alter the newbie jail to better comment the issues stated above. But, then again there's only so many limitations you can put on a user and if their goal is to make money through signature campaigns then they'll just grind it out.
