FWIW, whenever a friend or relative asks me for my email address, I usually ask why (unless the context of our conversation made it obvious). If they say that they would like to send me those kind of emails ("You Gotta See This Video!!!!!!!!", ""Cute Kittens Mothered By Dachshund," "Fwd:Re:Fwd:Re:Fwd:Re:Fwd:Wow!", etc.), I will give them an alias or a 'junk' email address, since I know generally what would/will be coming to it. That way, I won't be too terribly upset IF the address ends up in the "CC" or "To" field.
