Actually, I see this quite often at shops all over. One posted the full name and amount of unpaid bills on their very large outdoor sign. Others post pictures of bounced checks. If the mechanic is the shop owner, he can do what he wants with his property. And as far as I'm concerned, this applies to the web, too. If the web designer still owns the domain and server, go ahead and deface it to their hearts' content. If the client owns that stuff, however, the unpaid designer should just take back their work and let the client deal with the blank website.
