>>56960899>why should anyone have anything that can track usI'll tell you why: It's mighty inconvenient to have to request a username and password every time you need to perform an action while verified, and it's also mighty inconvenient to keep presenting the same screen of information that only needs to be displayed once again and again. That is why cookies were created.
Now, there are unfortunately ABSOLUTELY cases of abuse here, and many can be pointed out, but I don't think it works the way you expect it to.
The "short" of it is that the web browser cannot transmit cookies that aren't applicable to the site. That is against RFC 6265(
https://datatracker.ietf.org/doc/html/rfc6265), which defines what a cookie is. The only way for a cookie to be transmitted is if the browser requests a domain that it has cookies stored for.
Unless you have a malicious extension that is sharing your data without you knowing, the chances of 4chan cookies getting transmitted elsewhere are nil.
If you're worried about 4chan tracking you across the boards, they receive your browser's identification and your IP with every HTTP request, and can pair those together to track your actions, rendering this whole worry about cookies redundant at best.
There's also all sorts of other shit to worry about, fingerprinting is infamous because it does not require cookies at all, can't really be fully blocked no matter how hard you try, and can get you literally every single detail about the computer in the worst cases.
tl;dr: Don't worry about the cookies, because Javascript is a malicious force ready to wreak havoc on you.
