Say someone followed their poor advice, and could prove it (i.e. photo's of said board). Say then their house burn't down or someone got injured as a result. Could the people giving that bad advice as "presumed knew what they were doing" be sued under their professional indemnity insurance..
In short.. if you give professional advice it must be correct and you must be insured!!
