Does anyone get LOTTO NOTIFICATIONS from foreign countries?

I am so sick of this, it has started coming in by the tons and I haven't done anything different. They want all this personal information and I am tired of just deleting it. I haven't clicked for anything that would spam out my email address it just started, maybe a hack of some type? I am about ready to complete quit yahoo and stick with my hotmail account because of this crap. PLEASE HELP!!!
