Webcam Spies On You! (Hover)
I have almost always kept a post it on my computer to cover the web cam. I may just be paranoid but I feel there is too many things out there that I may not understand, like why others would feel compelled to spy on others. I know that it is possible and take precautions to prevent it. It is very unnerving to think about.
If it's a camera built into your laptop you may want to use a piece of electric tape. It stays on better and won't fall or be a fire hazard. If you have a webcam via USB then always unplug if not in use. Poor lady, I could imagine the shock on her face when she got the emails.
This is why we cannot have nice things, there are always someone out there in the internet who wants to be the peeping tom and stalk on what people are doing privately. Covering the webcam with electric tape seems to be the only solution to stop them.
