While I completely understand your interest in being able to delete profanity,shorten a URL extending into the margin, or fix a link, this would be an extremely controversial feature to add in. This feature would jeopardize a commenter’s trust that their comments would not be tampered with or distorted, and would potentially destroy the credibility of Intense Debate.
With that in mind, we cannot give blog owners this ability.
The search for improved commenting continues.
Update: Michael Koenig of Intense Debate responded to my questions on their forum and linked to this post. If you’re interested in this issue, go comment there to ensure Intense Debate hears your opinion.
