I know very well the difference, when I say that privacy is an illusion in the network. In the same moment when you go online, conecting to sites which are not your owns, they know what you are doing and from which site you came.
More people are confused what means browsing in anonymity mode in their browser, they think that with this they are Anonym online, but it's wrong, because this mode only delete the local storage, for webs which want to profile and track you it's irrelevant if you are in normal or anonymity mode.
All what you post online is públic visible, your mail direction is an unique identification which can be tracked easily in the whole web. Even in this moment a Google Bot is reading your posts in Lemmy and in every other SN and blog, very possible that it even know who you are if you had in the past an account.
You are not invisible in the network and because of this there also isn't a real privacy nor anonymity. Fact.
