This is not the only threat model I had in mind.  It is known that some
network monitoring actors pay special attention to everyone visiting
some web pages, and by sharing URLs we can make sure "everyone" visit
"every" page visited by someone, making sure those tracking visits to
some web pages get a lot of noise.  We also make sure the value of any
legal proof of "this machine own by this person visited these pages"
become a lot smaller.

Well, it really should impersonate some other user too. :)
