How do you put my Pingbox on my yahoo?

How do I stop Yahoo mail from allowing "Yahoo Groups " to put inappropriate requests from "ourSexyWeb Cams "?

• It says they have received requests from me to join these groups. I have never requested this and I have asked yahoo abuse to stop them from sending me this but they do not. I have forwarded the message to Yahoo abuse as yahoo told me to do but it means nothing. I have spamed every message sent, but yahoo keeps allowing this . What if I had a teenager in the home? What if my husband did not believe that I did not request this crap? Please tell me how to stop yahoo groups from writing these messages in my e-mail. I am eventually going to stop yahoo altogether for ignoring my requests to stop this or tell me how to.

• Answer:

  Click change your email preferences on the last line of the invitation and follow the prompts or: Click the My Email Preferences link on the My Groups page. Under Options, click on the Edit link for each email address you want to prevent from being invited/added to a group. Under Group Invitations, make sure the box is not checked next to Allow group moderators to directly add me to their groups or Allow group moderators to invite me to their groups. Click Save Changes when you’re done.
