The old security through obscurity. The attacker knows what kind of attack he's running, thus he already knows how it can be mitigated, if that's possible at all. Openly discussing it reveals nothing new to the attacker.* What appears to be the case is that DPR doesn't know how to mitigate it, which is why he mentioned several options in his latest post. That's why we need to be throwing out suggestions. *Not to mention that if we throw out enough ideas, he won't know which ones were implemented.
