Ask HN: Do webcam covers really work?

[namechecksout]

There's been quite a lot of buzz on online spying which gave rise to the creation of numerous webcam covers. But can they actually protect us? And are there any "stylish" ones that don't prevent laptop from closing and are also suitable for a smartphone? Because post-its don't do it for me.

You can cut down a piece of electrical tape and put that over your webcam. It's not rocket science.
