I went on Facebook (I know I know I know) and they are selling tinfoil hats.

The "Wavestopper" costs $88 Free Shipping!

(I checked. It is not an April Fools joke. Selling to people with "brain fog" feels a little predatory to me.)

@futurebird As someone substantially disabled by brain fog, that ad makes me want to perform some Luddite-like activities.
@futurebird I found their Amazon page and gave them a glowing (like nuclear waste) review, and reported their product page. Will Amazon do anything? Probably not. But hopefully it makes them do some damage control, at the very least.
