I've already dealt with FB.
It's called a HOSTS file. They don't get to set a cookie, they don't get to track me, & the only thing they can get about me has to come tangentially from friends postings. I've already asked my friends not to post photos of me, and any posts they might make that includes me should be kept to a minimum. I don't mind if THEY use the site, but I'd rather not have my data spaffed into their maw if at all possible. At first they complained but it didn't take very many privacy invading stories dropped in their laps about how FB fucks over it's victims/members/the public at large to get the point across. So FB doesn't get to know me, they don't get to track me, and they can just go fuck themselves with a Jovian moon for all I care. Do I advise my family & friends that FB is a bad idea? Yes. Does it seem to matter? No. Do I harp on them to give it up? Not to the extreme, but just enough to remind them "Here's the latest reason why FB considers you as grist in the mill."
As for Google I know they scan my email but that's the only place I allow their cookie to be updated; if it gets called on *any* other site then it gets blocked. They don't get to track me across other sites, they don't get to compile a list of my favorite haunts & hang outs, they don't get to listen in on my chats. The *only* Google branded service I use is Gmail & Search, and only the Gmail gets to update the cookie. (File set to Read Only FTW!) Yes Google scrapes my email in an attempt to learn all about me, but that's why I don't do anything important/personal via that avenue. PII via email? Not via Gmail it won't go. And if it weren't for Gmail, I'd just add Google to the HOSTS file as well. There's too many other search engines out there to use instead, and I won't share my PII with them either.
So FB & Google can try to track me all they like, good luck when I block your cookies, refuse your tracking bugs, & laugh at your feeble minded attempts to set pseudo-cookies to get around DNT requests. No Means No. I don't want you slurping up my data without my permission, so bite my shiny metal ass.
