A WebmasterWorld thread has several examples of people who say they have submitted re-inclusion requests months ago and still have not heard back from Google.
A few things here, we know Google Moves Reinclusion Request Form To Webmaster Central months ago. Also, I have tested out the reinclusion request myself with Jennifer Convertibles when they were delisted. And they got back in within a few days. Later, I did a post named Time Line To Get Reincluded in Google With Reinclusion Request where I showed examples of unanswered reinclusion requests and answered ones.
The new WebmasterWorld shows many examples of unanswered requests. I have heard Google won't answer all requests, especially those that still have violations on their sites and those that have repeat infractions - but can all those examples in the recent thread be in violation of the above? I don't know.
