Last century saw more inventions than the whole recorded history of mankind.
We tend to believe that computer tech world is the one that's seeing the most progress. Nothing can be further from the truth! Health and medicinal world is the one with the most new discoveries. And it's not really surprising if you read the medical journals.
This is especially true in the field of genetics. Of course the Electronic Technology sector is not to be dismissed either. We've seen an amazing expansion in this sector as well. But some of it is of a debatable nature. Reverse phone lookup would be a good case which has tremendously facilitated a previously hard task. In the past we had to manually search in the phone book. This would take a regular person several hours at the very least.
One can find out a lot of things using telephone digits. How easy is that? Unless the person protects this information you can get his home address and more. A mobile phone lookup might provide you with even more surprising information. GPS and Cell Tower search might disclose the current physical location of the cell owner!
You get so much information based on only one variable. The potential provided by this reverse phone directory lookup is absolutely amazing. For example you are now able to find the address of a person who has been harassing you over the phone. Also, you can find information on the company that called you and whose call you missed. You can run a reverse phone number lookup on an unknown number if you were expecting an important call.
It's sad, but evil doers can also use this service. A stalker might trace a victim's address based on a phone number.
In any case, even if some bad guys decide to use reverse phone lookup, it remains a very useful service, which we should all have access to. Their bad deeds should not prevent us from enjoying this service. In my opinion banning reverse phone look up, would be like banning forks, just because someone can use it as a weapon.
