yes, I still have no clue how that topic disappeared. I've looked through the logs (where all topic, forum and posts editing/deleting activity is logged) and couldn't find anything that was related to that topic.
I do have a backup of the database from a few days ago. I know for sure I have seen the topic a few days ago. I will try to extract that topic from the backup.
I do know that thanks to problems with the database/server of our webhost, I had to repair various entries in the database a few times the sunday and monday. This affected many new postings. I'm not sure if this repairing actually deleted posts or whole topics.
When someone posted a topic or thread during these periods of databasetroubles, and received a mysql error, sometime that field in the database became corrupt.
In short: I can assure you 100% that the original 'TCB - Philosophical Debate' topic hasn't been deleted by the moderators. We allow criticism to our moderating and rules (as longs as the discussion is respectful and doesn't turn out in to some sort of TCB bashing).
One warning though: we do not allow discussing of permanent or temporary bannings. If you want more information about it, contact the banned person. We do not hang out dirty laundry publicly.
