Well, as for spam war and other, the Scratch Team added the New Scratcher rank to stop users that just joined from spamming. Here is so far what the differences are between New Scratchers and Scratchers;
New Scratchers have the 120 second rule for comments rather than the 60 second rule to slow down spamming
New Scratchers cannot post images or videos on the forums
New Scratchers don't have access to cloud data
And more!!!
P.S. When a user joins, they become a New Scratcher and have to meet some requirements to advance to be a Scratcher.
See more about New Scratchers on the Scratch Wiki.

Hi! Sorry, but we already have a topic about the New Scratcher rank (right here).
