Not that SMS needs any defending, but the 'negativity' or 'borderline inappropriate comments' that you are talking about are more the result of sheer jadedness than cynicism. I've been a member of this board since 2006 and I have seen the same questions, the same expectations, the same search for loopholes come up time and time again regarding EP, PR and PEP applications. SMS as a moderator has doubtless seen countless more than me. When the same questions are asked time after time, and the same answers are provided, and the the same angry responses to those answers are received from the people supposedly looking for advice, then yes, the forum veterans will be jaded and some of their replies can be interpreted as 'negative'. Or 'blunt'.
If people out there are really seeking honest feedback and advice, simply using the search function would literally answer 99% of their queries. But, judging by the repetitiveness of the questions (just look at this thread for example), these advice seekers can't be bothered. It's annoying to say the least.
