It's only the DACH region to my knowledge and you can still do a lot to prevent spammers from getting the details.
That basically includes most of the default anti-scraping methods but since you only have one page to do it on, it's far simple to get 99% of the bad guys out (Spammers usually stop bothering once you get more advanced than ROT13 via Javascript or images designed to trip up OCR but still being readable)
Spam and scraping are not the problem, real people are. Getting a nutjob show up with a gun at your office because you are required by law to make your contact and address details public ain't fun, and not something that you can solve with ROT13 in Javascript.
Nutjobs with guns showing up anywhere to shoot up people is rare in my country to the point that I worry more about the extra electricity consumed by transmitting my imprint.
If somebody has legal beef with me, having a contact address to quickly resolve it is more important.
Besides that, you can always simply get legal with the registrar who will get them your address anyway (or escalate until you find somebody who knows who you are)
