Does the net need a better way to ferret out the truth?

A friend of mine recently had a horrible experience of misrepresentation of a vacation rental property called Casa Alta de Gastelbondo which apparently based on his description on the site referenced here is just a horrid place to stay.

On site like airBnB ratings can help.  But often places like this use other posting areas where ratings and reputation is fake or non-existent.  It will be interesting to see if anyone can solve the problem of mis-information online.
