Maybe you’re referring to @nyttypos? There were a few of them over the years, including one that (IIRC) tracked their *published* corrections. But they are super reluctant to admit errors that aren’t basic typos so I didn’t find it as helpful for the purpose of showing their so to speak true error rate. It’s a very labor intensive problem!
You would know a thing about that haha.
