Caroline, Caitie, and Jaycee echo my sentiments towards what references should entail. I would accept a reference from you ladies any day.
Personally, I don't always use references to meet a gentleman, especially if he's not verified via Preferred411 or Date-check. I've been the victim of vindictiveness and learned that screening without references was better for me. But I will contact ladies that I feel will be honest.
Conversely, I will give a reference to a reputable lady with no issue. If a lady is questionable, or just new, I will question him first before I respond. You don't want to incriminate him to a SO. I never judge a man by his 'type' because some men have no rhythm or rhyme to who or why they meet certain women. I have given references to BP girls because I believe in every woman's right to screen.
