I am very worry about new merit system. This is like killer rules for newbies like us. As i know that if somebody gives merit rating only then our rank will grow. Without getting merit from someone we can't rank up from jr member. So, who will give us those merit rating? Is this rules for avoiding new comers in bitcointalk? I am truly feeling too bad.

The only people it 'kills' are those that are unable to contribute anything worthwhile here which is the exact purpose it was designed for.
I'm curious, how bad was this "account farming"? Like what was it actually? I keep seeing it mentioned.
People were signing up with numerous accounts each just so they could join a sig campaign and bleed them dry by lazily spamming. One user had 200+ alt accounts all just rewording and regurgitating the same one line shitposts over and over one after the other, that's how bad it was. Sylon, the worst campaign manager on this forum, was paying them all to do so and that's why punishments need to be giving to shitmanagers otherwise nothing will change.
