Online directory legalities

Hello. I am a newbie here, so I applologize if this has been dealt with before. I am a board member of my HOA with 156 members. We have two board members who started a neighborhood web site on a Yahoo group. My main question is this:
Is it legal for them to publish a directory of all of the residents without their permission online or add homeowner names to Google maps online? If not, what law specifically forbids this?

The board voted (at their request) to make it the "official website" for the neighobrhood back in June, yet they refuse to abide by ANY board decisions. The offending board members claim on the site that it was "not created nor run by HOA board members (which they are)," and the board has given them instructions specifically NOT to post directories or Google maps with homeowner names labeled on them. They have done so anyway. They have been asked by several people multiple times to remove their information to no avail.

What kind of liability does this set the HOA up for? What should the rest of the board do?

Thanks in advance. Any help with this mounting problem is greatly appreciated!

Im not going to touch the web site issue itself, but just so you are aware, all of the info they put out there already exists elsewhere on the web. You can go to zillow.com for one thing and see that and a lot more. In most localities, you can view the assessors records for yours or anyone elses property including price you paid, value, building permits, picture, even in most cases a complete layout of your homes floorplans.
All of this is public information and as such, you cannot do anything to stop a inquisitive person any where in the entire world from seeing it.
Two things they should not publish are homeowners phone numbers and email addresses. Everything else is fair game.

Here are my two cents...first I believe that the homeowners should be asked before this is put out there. I know addresses and the info with it is public info but I will share a story...

We had a lady who had a messy divorce and didn't want any info on her published in a directory or anything because she was afraid of her ex finding them. True the info is public, but the more places you put it the better the chances are someone can stumble across it.

Zillow may not cover the entire country, but it does cover a lot of it. The photos are not necessarily very recent, but there is enough information that by plugging in a street address, even I can find the size and approximate value of a house, the legal description, and using the assessor's office, can find out enough more to know who owns it and what their mailing address is. Actually, all one needs is the street address and he site for the county assessor, and the info is availaable. Much more is available other places.

But yes, I agree, I do not want my name or address on the web, and if I could, I would remove it from everyplace I could find it. People have a right to privacy for any or no reason.
