Are you kidding me? Of course it is a SCAM, why would a Lawyer, Neuroligst or even a plumber be answering your questions at 2am? The last time I hired a plumber to install a water heather, he charged me $375 for 30 minutes worth of work.
Anyway, let me tell you about my experience. I had an unlimited access with Justanswer.com, and everytime I've asked a question, the answers were prompt but just something didn't seem right. So one day, I asked the same question differently to two different LAWYERS (yeah my a$$), and to my surpise, both LAWYERS' answers were verbatim, word for word, and the moment I asked what's going on, both LIERS I mean LAWYERS went offline.
I called their customer service, and May said that I was at fault because I've asked the same question, DAH!
These experts, lawyers, doctors or whatever losers they are, are probably somewhere in India, Thaiwan or some lala land googling, copying and pasting... WELCOME to the Internet World Wide Web aka Wacadoodledoo whorebags Wailord
