Just discovered such on a Royal Enfield bike forum I belong. A new registered "member" asks on their first post a cure to a plausible issue on a particular model of vehicle but with only brief details. The posts flood in with solutions but no further from the OP. The AI company that created the new registration is then able farm the forum to benefit their product by offering a digested version of the common answers to their users.
I wonder what safeguards there are against the likelihood of such being attempted on TM in the future, if it hasn't already
