I have noticed a marked increase in the amount of spam that I get since my sister tried to sign me up for the Bebo.com experience. Since they now have control of her hotmail address book, it only makes sense that they would spam everyone in it, including me. The sad part is that most of the spam I am getting now is "adult" related. I have never received much spam and I am very careful with my email addresses. Now I am receiving 3-6 messages each day that I believe are a direct result of Bebo.com. It just takes one person who doesn't have a clue to ruin it for you.
Please do not use Bebo.com.
