for the same reason..you got TER.  
About 30% of the pics on Craigslist aren't, even the girl, Half of the girls will either upsell, you, try not to deliver what you paid for, are bad at their craft, or, most commonly, are asking you if you are almost finished when you just got there. Also about one in 50 are going to have their pimp rob you with a gun. Your chance of getting a good quality and quantity of time commenserate with what you paid for is about one in 10 at best.

 Your chances on Backpage improve a little, but there is NOTHING like TER that virtually guarantees what you're gonna get. Just read the TER reviews where the girl get a 1,2 or 3. They are all shot in the darks off of Craigslist and Backpage that didn't work out. Why would you want to be another one of those guys saying "I should have stayed with TER and not wasted my money."

 And there are lots more who get taken that are either too embarressed to post their results on TER or just don't have the guts to post a bad review. I have had my feet put to the coals for some of the bad reviews I had the balls to post, so I guess I can't blame all the guys who don't post their bad experience. I gotta guess for every bad post from taking a shot on Craigslist or Backpage there are two that just never get posted.

If you like Russian roulette though, stay with Craigslist or Backpage. I played that game for awhile but finally decided that the 100's of girls on TER that are in my price range are enough to keep me busy.
