I am the owner of a hostel. I hate hassling guest about giving me reviews. The huge majority love it and pass it on word of mouth. The other night many guest were complaining about some of the dumb reviews my place received. SInce then many of them and others have posted on Facebook for past guest to write reviews. I got several good reviews that showed up immediately. Then several people emailed the hostel sating they wrote us great reviews. Now the good reviews are gone and the others never posted. What is happening? I have no way to contact Tripadvisor and ask.
