My concern is that Reddit can sell their profiling algorithm to other companies, who then can federate with Lemmy, mastodon, etc. to build profiles against users.
It's getting to the point where I may need to go back to cycling usernames every few years.
You should definitely do that anyways, you never know when some crazy is going to try and dox you. Changing usernames won’t really protect you from advertisers though, software will link the two identities together.
On Reddit, I was doing that, but every few months. At most, a year, before the username got canned.
