The CouchSurfing wiki was started by guaka (talk) in Autumn 2006. One year later guaka had been blocked from the wiki he started.
In 2009 CS management announced the deletion of the CS wiki. This took another 4 years.
The CouchSurfing wiki was finally deleted in January 2013.
Meanwhile Couchwiki was started by guaka in 2009 right after the announcement of the deletion.
