Over the last 4 weeks I've sent messages to 27 families who seem to be actively looking for childcare. I've had 3 responses. 17 of the messages have been left unread. However, many of the families still seem to be active with 'Last log in today' as their status. It's really weird. I'm a full member so they can reply for free. Are they fake profiles? Do other nannies who use the site have the same problem? If you're a parent who uses it, what's been your experience?
