Thank god. I get somewhere between 2 and 10 spam emails to my dedicated whois address every day. Requiring the publication of email addresses with every domain is absurd and serves no purpose.
The emails can be blocked easily, but the SMSes don't come from a number, they just have a random word in the "From" field and they use a random one each time, meaning blocking the "sender" is useless. They also come at all sorts of hours, so I can get 2-3 SMSes at 4am advertising Amazon crap, or other affiliate spam.
Spam seems to be getting worse and worse, despite all the efforts to combat it.
I have been very tempted to register an ultra offensive sounding domain name just to get someone at a call center to ask me about it by name :-D
I never answer the phone if the caller ID is unknown, so I may be missing some there also.
The idea of hiding the contact information never quite made sense to me. If you're a business, then you already have to provide an address of record to the state for certified mail to go to.
If, as a private citizen, I am running a controversial website then there are already institutes in place that will receive, process, and provide anonymity for your physical mailing address.
