We use an anti-spam software for this site that we have set to the highest level. This helps us to keep unwanted posts out of view as much as possible. The problem is that sometime innocent posts gets caught in the filter.

The system checks the first X number of everyone's posts. After you hit the magic number for posts checked, your posts are no longer checked. We check often for moderated posts, so don't worry if one gets caught in moderation.

The system check both the Akismet and StopForumSpam databases. Something in a post may throw a flag and get the post moderated, such as adding a link in your first post. While this may be done without intending harm, the databases take into account the number of spam posts that contain links in their first post and possibly add that as something to watch out for.

Anyway, while it may seem like an inconvenience to some at first, it is for the good of everyone here and we approve them as often as we can.

We have caught spammers, we have had legitimate spam posts moderated, and the system works. It may not be 100% perfect and while it has proven to be very effective, it may prove to be less than 100% effective against stopping forum spam, but it is an additional layer of security that everyone her benefits from.
