Pinch of salt required
I never take anything in TA as gospel any more than I assume that travel and accommodation providers web sites do not exaggerate aspects of what they have to offer. I tend to disregard grossly vitriolic comments on TA, particularly when they are one of only a couple of comments made - my impression is that all too often there is a 'getting back at the provider' motive. Similarly grossly complimentary comments from someone who has only ever posted one or two comments also raise a cynical suspicion. I use TA as a guide and temper my reaction to posts with discretion. One can always go to a forum for advice if uncertain about entries. To say that TA is no longer reliable is a bit of a broad statement to make just as it would be a risk to say that it is always reliable.
