[Blind-sysadmins] anyone have any contacts at yahoogroups?

Hello, Long shot, but thought I'd ask. I'm getting email from a yahoo group that I didn't subscribe to. First, I thought this was not possible, I thought everyone was on the you had to confirm you wanted a subscription plan. I've checked the full headers of the message and it's not coming in on a mailing list. I have atempted unsubscription and checked out this group on yahoogroups it's like something citizens for global warming, but I got resubscribed. As far as I'm concerned once can be an accident, twice is not, I'm wondering if anyone has any suggestions on what to do? Thanks. Dave.
