I fail to see how this advice applies specifically to sex workers. What I see is a (good) guide on how to protect your privacy and keep your personal data from prying eyes in the general case. You will be at risk of seizure, surveillance or examination if you're doing less serious and more passive stuff than a sex worker has to do.

EFF could maybe come up with some advice that will narrowly target sex workers in this case. They mentioned MyRedBook was used to screen clients and keep from predators, so perhaps some advice on how to do that now the site's down will be valuable?
