Because you're not posting on Reddit, for one.
For another, Reds have suffered quite a bit of verbal abuse that for the times they are reading threads, they prefer to lurk and then copy/paste the information in the threads into private instant messages to discuss the feedback without stirring the hornet's nest before deciding to respond.
While a viable approach, it makes feedback take longer to discuss rationally and in detail on both sides. That's why some champions randomly seem to get more attention from Reds than others but it's unknown approximately what chunk of information gets noticed and disseminated between internal testers and the balance teams, given how the Veigar and Evelynn reworks turned out while turning a blind eye to Lee Sin nerfs and Darius buffs for example.
