I don’t have specific info on what’s harvested, but I have had mine active for a while and I’m at 300k tracking attempts blocked in the last 7 days. It’s absolutely wild.

Edited to add - they don’t specify what is being attempted, just what each company is known to track generally.

I honestly didn’t notice them until this comment chain, and missed them terribly from Relay. So, uh, thanks, y’all? Lol
