No. Newbie-jail won't come! SaltSpitoon said it well!
Newbie jail causes a huge amount of issues. People complain about removing newbie jail, but it really didn't do much to prevent spam. The issue with spam doesn't come from genuine newbies, it comes from account farmers. If you are managing 100 accounts, a 3 hour wait means very little to you. If you are trying to learn about Bitcoin as a genuine newbie, a 3 hour wait can do enough to convince you its not worth looking into. If newbie jail was reimplemented this second, the forum would indeed get better, for 3 hours that is, then the waves of accounts hitting the boards would be the same as it was before. In addition, whitelisting is a huge drain on staff resources.
If you report one spammer, all of their accounts get banned.
