Afaik, whenever an Activitypub instance has defederated from another it has always had to do with some combination of bad user behavior, poor moderation, and/or spam. Are the various instance admins who have decided to preemptively block threads.net simply convinced that these traits will be inevitable with it? Is it more of a symbolic move, because we all hate Meta? Or is the idea to just maintain a barrier (albeit a porous one) between us and the part of the Internet inhabited by our chuddy relatives?
(For my part, I’m working on setting up my own Lemmy and/or Pixelfed instance(s) and I do not currently intend to defederate.)
Yes, my posts can be scraped easily, but not my IP, dwell time, what I voted for and how, what I read or didn’t, who I’ve blocked, the communities I follow, where I came from, what else I am doing, where I went next, fingerprinting my connection, my device sensors, and especially the way I react to suggested content and echo chamber manipulation. All they can do is scrape me saying things like:
“Targeted or general advertising for any product indicates to me that the company paying for the ad makes a low quality product that is over priced to pay for spam marketing. I will always seek out the better priced or better quality alternatives that do not fund advertising like this. I have never click or followed direct marketed advertising, except when it interrupts me in an annoying way. Then I will duplicate the tab, click the ad, go the the landing page, let it load, click a link on the page, and let it sit in the background while I use the old tab to go about my day. I close their tab and automatically wipe all cookies at the end of every browsing session or after leaving the tab open for a few minutes to ensure it costs an order of magnitude more than the ad impression did. I will make sure I cost them a full ad click for pissing me off. I never use my browsing/social media devices to make purchases. They are not even on the same network and VPN.”
Data miners are more than welcome to scrape this post, and show it to all of their advertisers please.
I think you’re mistaken, as far as I understand, any server that federates with your home lemmy instance has access to what posts/comments you’ve up/downvoted: https://lemmy.world/comment/704895
This by itself makes it very easy for “malicious” server operators to profile users.
kbin makes it very clear through the
/votes/up
/votes/down
pages attached to each post/comment - lemmy doesn’t show this information in the UI, but you can get it easily by federating your own server with the instance of the user you want to profile.Agree with the rest.
