This is a letter I received from a fellow in New Jersey. It caused a huge thread on the defunct amcforum.net website after it was known. 
Please keep in mind there is only one SC/360 Registry and I never ask you for information, (it is up to you to participate!) much less share your information with others, just the basics to document and research these vehicles. 
If someone asks you about your vehicle or wants data, and you wish to share that, it is fine, otherwise you could end up in a situation as below which is how cars get stolen, people get stalked and why ID theft is such a huge problem in this country. And I sure as hell won't show up at your door.

Subject: Re: My SC/360

Eddie,
I have a problem which needs to be addressed immediately. I retuned home on Sunday to fine two men peering in the windows of my garage, before I could even get out of my truck, the older one came over and told me he was here to buy my SC/360(which is NOT for sale!). I told them the car was not for sale, but they said they wanted to see it anyway. I didn't know these two from Adam, so I politely refused and asked them to leave. The older one told me again he was here to buy the car no matter what it took. I asked him how he even heard about the car, and he told me he tracked it through the VIN and my Name on your website, and got my address from the internet. I told them again, I would not show the car, and that they should leave, but they refused to leave until they saw the car. I ended up calling the police, and they finally left before they arrived. I gave the police their license plate#, which I learned today was stolen. When I came home from work tonight, my neighbor said there were two guys playing with my garage door which fit their description, they left when she said she was calling the police. The point of this letter is that someone, for some reason, is attempting to steal my car based on information off of your website, and I would like any information about me or my car to be removed immediately please. I'm sorry, but this is what I feel needs to be done at this point to guarantee the safety of my SC/360, and the other cars in my garage. By the way, I happen to belong to a 400 Firebird registry online which does not reveal the VIN of members' cars or their names if that is so desired. I would respect your privacy if it were the other way around, and hope you can do the same for me. Thank You. 

Sincerely,

(name deleted)

Since I received this letter, I changed the way the SC/360 Hornet Registry documents vehicles and what type of information is on my website. Again, if you are approached by someone wanting to 'document' you car (and it ain't me) please keep above incident in mind. Thank you for participating in the SC/360 Registry.
