It takes considerably more time before DoH/L bots are able to start generating profits as they're gated behind both MSQ progression and DoH/L levels, unlike the conventional gil farmers who are ready to go full farm mode as soon as they're done with the ARR MSQ.

That said, the former could be kept in check if they adopted an investigation routine that actually caught them with some semblance of frequency...and they need to if they don't want the Ishgard Restoration rankings to be a joke.
