If you are the owner of a Yahoo! Group and want to stop members from connecting your group to Grouply.com, there is a procedure here to do that:
After an outcry of complaints from group owner-moderators, Grouply made available this web page they call “Grouply Access Controls for Group Owners.” Reportedly they intend to add new “controls” to help you prevent grouply.com and its subscribers in your groups from wresting from you the control you already had as a Yahoo! Groups owner-moderator.
