Generally you don't want to give more information to potential attackers. The reason is because it allows improved matchmaking of criminals and victims, and allows criminals to improve the efficiency of their crimes. A criminal that's looking for guns could go outside your house, wait until you leave, then rob you looking for the guns and getting out quickly (with a fence ready to buy them). A criminal looking for something else could see that you're not on the list, break in with their gun while you are home, and do who-knows-what to you. Sure, there are exceptions. Maybe you want a "beware of dog" sign or a "closed-circuit camera" notice that might push the criminals to keep looking for their next victim. These notices are best to prevent crimes of opportunity, and probably better posted on the house than in a leaked database online.
