Generally, posts are flagged as spam if they appear in rapid succession. Say you post three regular discussions, a comparitive and then a poll all within ten minutes you're more than likely going to end up on the radar of one of the many people who are looking out for this community. This is especially true if your questions are about products that have a ton of reviews and you're asking something that could easily be answered by reading said reviews.
You can contact Kristi/Zuul with any questions you may have. That is, if she hasn't gotten to you first.
