In a case like that, sure. But they don't provide any information even when they want the publisher to make a change. Our Adsense account once got suspended because ads were appearing on pages that contained user-entered search keywords. Occasionally users would enter keywords that google considered 'naughty', and didn't want their ads appearing alongside. If they'd just told us that, we could have added a filter to not show ads with the list of keywords they had a problem with. Instead it was an infuriating, weeks-long process of pulling teeth to get clues as to what the problem might even be, and then making a list of every conceivably bad word we could find or imagine (admittedly that part was a bit fun) before we were finally able to get re-approved. And presumably we only got that much leeway because we were a reasonably large account.
