I can’t even copy a url without being tracked. When I copy the urls, they get copied with tracking ids, i don’t know what they are doing with this data but I think they are creating a mesh table of people, their relatives friends etc. So, I am done, I will delete all the social media in a few weeks, use my phone only with federated apps.
This is also a great way to dox yourself. With a number of platforms that do this, opening the link will greet some users with “see what else USERNAME is doing”
So if you share a reddit post with a family member, they might learn your Reddit username. Likewise if you share a tiktok or instagram post on reddit, then people might see your real name.
