This is something that flares up every so often. I can only assume the people who spy on others are so bored that anything is better than what they have in their lives. However, the notion that someone might be weird enough to watch me sit at my desktop is unnerving. Yes, I do have a webcam stuck to the top of my monitor with bluetac, a semi-sticky putty type adhesive a tad like gum. Over the lens of my webcam is not another lump of bluetac. It will come off easy enough when I want to use the device and in the meantime? Good luck looking through a sea of blue.
