Problem
With the removal of the Child Protection portion of the tool T227715, the tool removes any highly sensitive information (correct?). It may not even be necessary to maintain a history of what has been reported.
Proposed Solution
The tool can be simplified to be a simple form that posts to Lumen and the makes the necessary posts on the specified wiki. This can be done as a simple tool on Toolforge. The database as well as the API can be removed. At that point, it might be faster/easier to rewrite the tool using Nuxt.
