How can a canoeing group be transferred out of the "Adult" category?

Back when Yahoo first created the "Adult" category, my canoeing group was transferred in there. This made the group nearly impossible to find and the members don't like the "Find a **** Buddy" advertisements supplied by Yahoo Sponsored Results. The usual method of changing a group category doesn't work in the adult category and Yahoo doesn't have any help available. One of the moderators even tried reporting Yahoo Sponsored Results to the abuse people as inappropriate postings.
