Ian, I'm sure Jim would gladly help other pike anglers if they asked for advice on venues, baits, rigs etc but the point he's trying to make is that big pike are becoming rarer (Chew Valley aside) due to increased angling pressure, poor handling etc so it's in the best interests of the big fish for the location of big pike captures to be kept quiet, otherwise that venue where a big pike was caught would certainly see increased angling pressure which would be detrimental to the big fish.
However, I also see your point of view regarding non informative catch reports (big pike captures not included of course!) from NESA members (there's usually a few in the shore angling reports) where they only serve as an ego boost to the person who has written the report then followed up by several replies of nice fish mate, cracking catch pal blah blah blah zzzzzzzz.
