I echo Steve's thoughts.
Regarding Adi's point I have put a note on the web alerting members, although it's in the carp section, and a full copy of the rules have always been on the site, but I guess no one reads them either before or after joining, which is a bit silly.
Stuart I also understand your point about policing, but we have always tried to be relaxed rather than aggressive
regarding rules and if everything is running smooth let it run. However barbed hooks demonstrate the folly of doing that, but checking everyone's hooks every time still seems a bit OTT.
I've always adopted a live and let live view which means people can destroy their livers, lungs or brains for me, I've had a go at all of them in my younger days....as long as they don't annoy others. We have to act however if we receive a complaint, as you've experienced, and then we have a procedure to follow, and we always seek both sides of the argument, but the outcome can vary tremendously dependant on circumstances.
