@crashdoom I'm generally against automated moderation having been shadowbanned on other platforms for no reason I can identify. These scripts are never infallable nomatter how well intentioned. A computer can be trained to recognise keywords but it can never understand context.
Having said that, I do appreciate the urgency to do something. If you do go ahead with it, I would ask the following:
Make sure the user is informed of any action, never use shadowbans.
Make sure there is easy access to human review in the event mistakes do occur.
