As we are concerned about privacy, I am curious just to understand if lemmy can be at some point exploited by someone to profile its users.

That may not be possible with web technology.

Browsers send URLs to web servers. The web server has to have the URL the user wants in order to serve a response; and it has to know who the user is in order to check permissions (e.g. don't accept a moderation action from a user who is not a moderator).

This inherently creates an opportunity for the web server to record any details about that exchange.

What if database entries are encrypted, so that a person cannot match email and username with the requests in the urls?

Users' client create encryption key on client side. Would it make sense?

It's still a fingerprint, the most vague information correlated with other data points can make a useful fingerprint. This is how a lot of the companies can track you even if you aren't logged in, you using any service creates a pattern that with enough aggregate data can be used to approximate who you are.

Thanks, it looks like privacy on internet is really a mirage
