Open posting permits less rigorous items as well . The derisive term for this on MetaFilter is '' NewsFilter '' ( or similar - Filter names for specific news topics , e.g. '' IraqFilter '' ) . Nevertheless , it is accepted that some discussion of current events and politics in particular is inevitable , and a certain level is tolerated . If more than one post is made about a news topic , the extras are often deleted and discussion is redirected to the " canonical " post about the topic , usually the first one made . Important news items or political arguments can turn into very long discussions , such as 9/11 ( 2001 ) , the London Bombings ( 2005 ) , and Hurricane Katrina ( 2005 ) — which generated over 80 front page posts in about a week . The first example of this was arguably the 2001 Nisqually earthquake
