These and Instagram seem to be the main locii of conversation for a topic I’m interested in. Instagram is a no because Meta. Just trying to keep myself off of the big data mining sites and search results are a bit of a hot mess.
Edit: Please, no more splaining how there isn’t any privacy on the net. There’s what can be scraped, what can be gathered from cookies (which I’m as careful as I can be about), and there’s what we make it easy for corporations to collect by using their products. I’m asking about the latter for Discord and Tumblr. It’s not that I’m unaware of the general problem (otherwise I wouldn’t be asking), it’s just that I’m out of the loop on specifics for these sites.
“When you’re not paying for a product, then you’re the product”
That should explain Tumblr and free Discord. You should expect them to gather all data possible about everything you do, their apps to gather all information from your device that you might let them, then sell it to “the big data mining sites” that everyone else is also selling to.
“Enshittification allows double-dipping”
That should explain paid Discord. Even when you’re paying for the service, they can make even more by also selling any data they can gather about you.
As for cookies, they aren’t required to track you, or to create a shadow profile:

As far as I can tell, there is no meaningful difference between the surveillance levels and data sales of Meta, Google, Discord, Tumblr, ex-Twitter, or Reddit.
