Brooke Linden, I dought that you will read this but I would like to toss a few things you way. Something to think about.
Key word filtering does not work and should NEVER be suggested as a solution to a problem like this. The person who suggests it should be FIRED!!!!
You see, back about 10 years ago AOL decided to do some key word filtering and to remove everything from there network that was not kid friendly. So they created a big list of BAD words, ran the filter, and deleted all the adult stuff. However, in there zeel to be "Kid Friendly" they added the word breast. I am sure they thought it was as bad as t*t, or b**b, what they did not think of was all the ways this word could be used. So away went the "Breast cancer support group" and the "Breast cancer survivors group".
Now to my second point, I have a teen daughter as well as a brother that is a teen. From talking to them I can say that your "Adult Verify" system is about as effective as a screen door on a submarine. It would seem that EVERY TEEN out there is well aware that your system will adult verify them provided they look up the information of a dead celebrity and enter it. Every teen I know that is on the grid has an adult verified account.
So, from my point of view most of what you are trying to do is a waist of time. It has been tried by many companies and no one has ever gotten it to work right. Most give up and go to simply asking "Are you over the age of 18" If they say yes, they get adult access. If it is a teen and they lied to you, it is not your fault, you asked. They also give the people the tools to self regulate. Then kick and ban the troublemakers who repeatedly violate the rules.
