paperback, I have sticky notes around my iMac, some don't stay stuck so I use a bit of blue-tak.

When I joined a zoom concert last year, my image was very blurry & I had to try & rub off the residue of the blue-tak. Didn't work & everyone else had a crystal clear image & mine stayed eerie ...

Which of course means if THEY are spying on me they won't see much.
