your source is exclusively about aggressive behavior...
it uses the term "arousal", which is not referring to sexual arousal, but rather a state of heightened agitation.
provide an actual source in support of your claim, or stop spreading misinformation.
yeah, no.
thing is: YT/google/the data kraken knows you regardless of wether or not you're logged in.
they track everything from IP, to location (even just approximate based on IP), screen size, browser, OS, and sooo much more.
being logged in makes it easier to track you within a site, but you get tracked regardless.
