The fact they took down their names though makes me believe they might be telling the truth. Wouldn't scammers just not put their name up to begin with or try to pass off those fake names as being legit?
You have a good point but you cant hold it against others who would have thought of the other logical reasons for that action -- which could run to thousands-- and were not comfortable with same. It only makes sense to ask questions in order to make an informed conclusion rather than relying on some assumptions that has been drawn up based on sentiments (or not). Its the beauty of dialogue.
