The blogging system now enforces a limit on the number of categories, comments, trackbacks, articles, and moblogs per blog in active and trial state. These limits do not constrain legitimate publishers but do prevent spammers from abusing the system.

The anti-spam features and functionality are intended to make the blogging system more secure against the attacks of spammers so that system performance will not be adversely affected by spam attacks and that publishers and readers will not have to view offensive spam content. The anti-spam efforts include the ability for publishers to promote candidates to the global blogging system Blacklist.
