This is like plane overbooking. Airline companies could do the right thing and just sell exactly the seats left on the plane (in this case, the OF creators could put a limit to the people being able to DM them) but instead they choose the extra profit by selling more tickets than there are seats (OF creator allowing an ungodly amount of people to flood their DMs) and just take the blame the few times the statistics goes against their favor (someone figures out they have been talking with an AI/employee)
