How do you keep msgs in private groups private?

Why would Yahoo Groups keep sending me spam to their adult porn groups? Is this a new practice?

• I've gotten about 12 of these in the past week, always a different group all the same subject PORN ! How can I get them ( or you if your reading Yahoo) to stop? I thought about marking it as spam but there are other groups I do subscribe to. And being that the sender is marked as Yahoo Groups I'm afraid I will miss out on something I want.

• Answer:

  Yahoo isn't the one who directly sends these, it's group owners that do. if you don't want to mark the prevention manner, then all you can do is either ignore them, or report them since it is a TOS violation to send group invites to people you don't know. I also don't do the prevention, and when I get these invites I report them, include the mail header. yahoo will delete these groups. How can I prevent moderators from adding me to their groups or sending me invitations? http://help.yahoo.com/l/us/yahoo/groups/original/members/email/email-44.html?terms=prevent+adds abuse form http://help.yahoo.com/l/us/yahoo/groups/original/members/forms/abuse.html;_ylt=AhXX.KHPMNkKINl0AVTzUFsACXdG?from_url=http%3A%2F%2Fhelp.yahoo.com%2Fl%2Fus%2Fyahoo%2Fgroups%2Foriginal%2Fmembers%2Findex.html
