I do - I work with this daily. It would be a massive uphill battle to even prove in a court that your whole post history is considered "identifying". It's a case-by-base basis. On top of that, your data could still be easily stored and simply no longer associated with your email (but still can be kept if the previous cannot be proven about identification). Then this would have to be tested, on a that same case-by-case basis, for every single user that made a request.
To quote yourself, "please don't state things if you don't know what you're talking about."
