GG US privacy laws.

/GG US privacy laws.

So companies can now follow you around the internet with their ads even easier thanks to Google’s Customer Match service. Awesome.

For the record, this is why I don’t give companies my Google account email address when they ask me for addresses; I have a custom domain with a catch-all email (i.e. everything sent to literally any address goes into the same mailbox) and then use a new address for each website I sign up to (e.g.,,, and so on). That all gets forwarded into my GMail account, but the addresses aren’t actually associated with that account.

For bonus points, it also lets me know who leaks my passwords and who sells me address to spammers. Awesome.

It’s not foolproof privacy–data correlation would be still possible if anyone knew which domain(s) I use for this–but it knocks out some of the low-hanging fruit like Match.

Oh, and incidentally? The title is because Match would be illegal in most major non-US jurisdictions; countries with sane privacy laws don’t allow the non-consensual sharing of PII (which includes email addresses) with third parties. Just, yanno. So you’re aware.

    I used to do the name+identifier@gmail trick (which of course wouldn’t work in this scenario as it’s still all Google), but stopped bothering after a while because it was getting tricky to handle so many variations of an email for so many different websites. I probably shouldn’t, but have mostly resigned to the fact that it’s impossible to be untrackable by companies online.

    Tangential rant, though? I very recently received a call from a telemarketer who said I won some opportunity from purchasing on eBay. They have my number and full name, and probably know where I live now, too. I don’t know which seller gave them that information (assuming they actually got it off eBay) and can’t think of a way of preventing that if I need stuff to go to my house. Just great. Just fucking great.

    Just out of interest, have you actually caught any websites leaking your information through your email trick?

      Ugh. Yeah, telemarketers are the worst. We don’t have a landline phone for exactly that reason. Even though I’ve had the same mobile phone number since I was in high school, it never gets spam called. But when we did have a landline, the only calls we’d get on it were spam. Go figure.

      have you actually caught any websites leaking your information through your email trick?

      I have, yes! Though admittedly not for a while because Google’s spam filter is too good, heh. (And also because, nowadays, spammers tend to just guess addresses more than buy them.)
