It seems every lottery jackpot winner whose identity is known complains of the deluge of mail they get from people begging for money for their own personal "crisis".
I remember seeing a lottery winner on tv (might have been TLCML) showing a duffle bag full of mail and saying he gets piles of it everyday.
I would have to surmise that these people don't just pick out one person to do this to but rather every winner whose address they can get.
And for all we know, it may be a lucrative endeavor.
Personally, I don't think I'd want all those people knowing my address.
If your state gives out your personal info, I guess all you can do is try to take some kind of evasive action.
Because they also show up at your door from what I've read in the past.
