Turning off the machine translation and reverting all the changes it made seems pretty actionable to me. They can turn it back on when issues are addressed.

Indeed. Turning it off would still satisfy marsf's requests:

- I prohibit to use all my translation as learning data for SUMO bot and AIs.

- I request to remove all my translation from learned data of SUMO AIs.

Before fixing it and re-enabling it in some capacity, they could work with marsf to find a solution.
