Yahoo email question


New Email
I have had a Yahoo email account for over a decade. In the last year or so I've started to get a lot of these weird cryptic emails. They are basically gibberish and my name or email address doesn't even show in the Sent list. I think it has something to do with that Y Conversation thing they started some time back, but I never signed up for that and I'm sick of these emails. I have no idea how to 'cancel' it either. Any ideas? Thanks, Loridae
