Requesters talk to each other and they can talk to mturk... there's a reason why the phrase "act professionally" is such a pervasive one in the business world. If you are turking for money... then this is your business. You should consider acting professionally. Part of that is engaging people appropriately, even when they've done something you don't agree with or don't understand. Adulting can be hard sometimes... but learning that you have a limited number of fucks to give before they lose all value, and then giving them judiciously when there is a real need is a valuable skill.
