I hope that everyone who's currently saying that you have to add a header to avoid Google's FLOC thing realize that the header won't have any effect unless you're serving ads, right?
For the Origin Trial they are running it only includes your domain if you run ads in the first place
This is plainly documented in the Github repo
@g that should be X-Fuck: Google

@ChlorideCull i think i remember reading somewhere that the x- isn't needed or recommended any more? but idk
@g @ChlorideCull RFC 6648. Yes, there's an entire RFC just to say you shouldn't do the X- thing. https://tools.ietf.org/html/rfc6648
@terrana @g I still tend to use the X- prefix for jokey stuff that has zero chance of gaining any wide use, just to avoid collisions (although I'd like to see the RFC that introduces the Fuck header).
RFC 6648 makes sense when it comes to seriously trying to extend or implement a protocol, as the issue is with it never being able to be removed, but I like for my jokes to not actually potentially cause issues in the future.

@ChlorideCull It's not going to hurt to add the header to though, and frankly I wouldn't be surprised if Google changes their policy on this
@gulfie It's going to hurt if the header changes in any way as the spec isn't finalized, but because "I already blocked it" people don't change it, and thus end up with it unblocked by the time they actually need to block it
They are unlikely to change it for the origin trial, as things are far from locked down in terms of how the opt out/in would even work in practice - right now you can effectively opt out from producing any meaningful data and still use the FLOC IDs, which means ad providers would cannibalize each other.
@ChlorideCull I think the confusion comes from the fact that the README says the exact opposite even though issues and Chromium docs agree with you
All sites with publicly routable IP addresses that the user visits when not in incognito mode will be included in the POC cohort calculation.
@leo yeah, that paragraph is 7 month old, unlike the privacy analysis doc
I mostly caught this because I've been following this since mid-February
@ChlorideCull i did not, no. im still leaving in the Fuck: Google header tho
