LiquidThreads does not keep a complete edit history for users. If user B changes user A's post, this is logged in the thread history, but not visible as an edit by user B in Special:Contributions/B. This is a major issue in cases of vandalism, because it will allow users to change Lqt posts all over the place without having a proper way to find what was changed where.

Example is the topic change that is logged in [1] but no where to be found in [2].
