Is it? I always name my personal belongings (umbrellas et al) so if I forget them somewhere public and whoever finds it is a kind soul, they can return it to me.

Of course nobody _else_ should be forced on sharing details just for this kind of occasional utility, I'm not claiming that.

Am I supposed to make the assumption for you that because you put your name on your lunchbox, you prefer to make available your name, phone number, and address on your website whois?

Honestly, I think you should take social engineering more seriously if you think the benefits outweigh the costs.

Like someone removing their front door because it might encourage someone to drop by for some stimulating conversation.

For example, the author of the "Amazon Backdoor" post a while back suspected that the attacker got their address from a whois of one of their domains.
