For the last week, LinkedIn kept showing me ads for some specific dental procedure, near the top of my feed.

It's an optional follow-on procedure for the dental surgery procedure I had scheduled for this week.

I'm much more careful than most people about keeping Web search and browsing history private. But there's a chance that last week I browsed some question about the scheduled procedure, from my less-private Web browser, rather than from the Tor Browser that I usually use for anything sensitive that doesn't require identifying myself.

If I didn't make a Web OPSEC oops, it looks like maybe someone effectively gave private medical information to LinkedIn, of all places (an employment-matchmaking service, where employers are supposed to be conscientious of EEOC and similar concerns).
