Lies and the net

BUZZ!!(Friend's name): Tony and Linda just told me to try these red tablets I saw at their place, Acai berry. They get them for $5 and they swear they lost weight, 23 pounds in two weeks. Anyways, I seen them both and wow they lost a lot of weight it really shows. http://darkclap.com

This is a message I received from a friend on my Yahoo Messenger. It is not the first time I got such a message and I know my friend would not send me such a message. When I checked with the supposed sender, she apparently knew nothing about it. I have therefore come to a conclusion that the YM system is not safe (actually all of us are aware that it is not safe) and there is a need to clarify with friends should their messages sound odd and unfamiliar. Someone is using our identity to send messages that may not be pleasant to the people on our lists and yet we are not aware of it. I am posting this note just in case some of you are not aware of such situations whereby people use others to spread lies on the internet.
