This question has also come up.
Deletions only count from today forward. And - only the ones that you'll get a warning with. So, double posts, quoting a deleted post (but your post is acceptable ... but remember, it's an all/nothing ... so quote a deleted post, yours will get deleted, too), borderline classifieds, even blatant classifieds - if it's your first post, those kind of things won't count - OTOH, if you're someone who pushes the limit at posting topics in multiple areas over and over and over again ...

We do have some discretion!
