Hi
There is an automated system which has been configured to pass posts to moderation if they activate the SPAM BLOCKER.
Bad Word Count - Rates spam factor based on number of occurrences of configured bad words
Forbidden Words - Rates spam factor based on the existence of configured forbidden words
Link Count - Rates spam factor based on number of links (href's) in the post
Community Servers Explanation:
With the prevalence of SPAM (unsolicited content), and the interactive
and dynamic nature of communities, community sites are large targets
for automated SPAM attacks. Community Server has an innovative rules
engine that evaluates all incoming content (forums, blogs, photos,
files, comments, etc.) and can determine the likelihood of that content
being SPAM. Actions can then be taken to put the content into a
moderation workflow, publish the content automatically, or even delete
the content.
I am investigating the situation and will do what I can to prevent future problems occurring.
