My blog with Joomla is doing well - lots of comments (4000 over a 2 year period). This is because I allow anyone to comment and fight spam with Akismet and re-captcha so that I get no spam. Many of the posts are about financial issues so many of the comments include financial words - costs, fees etc and several times people commenting have found their comment rejected. Testing shows that a high density of financial words causes Akismet to reject the comment. When Akismet is used in WordPress, rejected comments are listed as being "for moderation" but in CompoJoom, Akismet works with no visibility. There is no way to correct false positives. A feature to moderate comments rejected by Akisment would be cool.
