An example of what I would consider resort bashing in addition to the discussion above would be if I started a thread asking the forum if they know where a good place to get an ice cream cone was when staying at the Beach Club Villas and the responding replies said something along the lines of: I would never be in the beach club area to get a cone because of the lack of crescent lake views, tiny rooms, no monorail, yadda, yadda, yadda.... a response that has nothing to do with the intent of the thread by the original poster (I know threads get off track, I'm as guilty as anyone else on that score) and is directed deliberatly negatively towards a specific DVC resort in a repetative ongoing manner with the same issues reported over and over by the same poster in multiple unrelated to BCV negative issues threads. The statements may very well be true, but when way, way, way out of context to the discussion and brought up only with the intention of goading or non-trip report complaining, I see that as an example falling into the rhelm of resort bashing.
If a thread is comparing the pros and cons of a resort with balanced discussion, or reporting a bad resort experience to let others know of a problem, I don't see that as resort bashing.
Just my $0.02.
