Entirely dependent on the lottery, the only one I have heard of this being a thing is the main US one. You can remain completely anonymous in the major European lotteries for example.
The US and Canada Lotteries publish the winners because it is a public record that they did in fact pay out. The European commisions that don’t publish have to face yearly accusation that they don’t actually pay out and then have to publish tax forms that do infact reveal the identity of winners.
If you win you still lose cause most places publish your name. This really is a field where wining is losing.
The money just make you an easily identified target or mark for the audience.
