Class action against Yahoo for their email

I host 5 web sites on one server. I never spam (my sites are all double opt-in and I have never ever purchased email lists). In spite of numerous attempts to get the issue resolved (filling out their forms, directly emailing them, etc) they continue to bounce my emails. This is affecting my work, my free web sites, and, more importantly, my work on the boards of directors of Community Counseling Centers of Chicago and the American Foundation for Suicide Prevention.

I am certain I'm not the only one affected. Anyone interested in forming a class for a class action suit against Yahoo please contact me.
