Problem definition:

When Mollom blocks spam, it is not always clear why it was blocked. Users get frustrated as it happens sometimes that a site blocks "ugg" in the blacklist and that words such as "suggestions" are also blocked. The site user is frustrated and the site owner is frustrated because both can't see where this comes from.

Solution:
We should expose some stats and some information to the site-adminbistrator when it was blocked for content, blacklist or other reasons. We shouldn't go in depth on why it was blocked but we can add some of the information to internal statistics. When a comment was blocked due to a blacklist, the site owner has a right to know. When a comment was blocked due to content, and what mollom has learned, the site owner has the right to know.

Potential Problems:
Mollom doesn't return that information, we should engage with the Mollom engineering team to see if this is something that can be added.
